A. 79
B. 87
C. 86
D. 76
Answer : Option D

Explanation :

Average = total runs / no.of innings = 32
So, total = Average x no.of innings = 32 x 10 = 320.

Now increase in avg = 4runs. So, new avg = 32+4 = 36runs
Total runs = new avg x new no. of innings = 36 x 11 = 396
Runs made in the 11th inning = 396 - 320 = 76

Then, milk : water = 40 .
20 + x
Now, 40 = 1
20 + x 2
20 + x = 80
x = 60.
Quantity of water to be added = 60 litres.

% increase per year = (increase per year/ initial population) × 100
=> (8750 / 1,75,000) × 100 => .05 × 100 => 5%

A.100
B. 200
C. 180
D.400
Answer: Option B

Explanation:

Let the number of students in three classes be 2x, 3x and 5x respectively.
Due to increase of 40 students in each class, we have

3x + 40 5

⇒ 10x + 200 = 12x + 160
⇒ 2x = 200 – 160 ⇒ 2x = 40
⇒ x = 20
∴ Original strength
= 10x = 10 × 20 = 200

The sum of the digits of a two-digit number is 15 and the difference between the digits is 3. What is the two-digit number?

A. 69
B. 78
C. 96
D. Cannot be determined
E. None of these

Answer: Option D

Explanation:

Let the ten's digit be x and unit's digit be y.
Then, x + y = 15 and x - y = 3 or y - x = 3.
Solving x + y = 15 and x - y = 3, we get: x = 9, y = 6.
Solving x + y = 15 and y - x = 3, we get: x = 6, y = 9.
So, the number is either 96 or 69.
Hence, the number cannot be determined.

C. 20
D. 133
Answer: Option D

Explanation:

Let the number be X.
Then, 4/17 of 17/19 of the number is (4/17) * (17/19) * X = (4/19) * X
3/38 of the number= (3/38) * X

Given:

the difference between these two values is 17.5.
Hence, [(4/19) * X - (3/38) * X ]= 17.5
Solving the equation, we have X=133
Therefore, the number is 133.

The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?

A. 4 years
B. 8 years
C. 10 yearswrong
D. None of these

Answer : A

Explanation:
Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.
Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
5x = 20
x = 4.
Age of the youngest child = x = 4 years.

Father is four times more than the age of his daughter. If after 5 years, he would be four times of daughter’s age, then further after 5 years, how many times he would be of his daughter’s age?

A. 1.5 timewrong
B. 2 times
C. 2.5 times
D. 3 times

Answer : C

Explanation:
Let the daughter's age be y and father's age be 4y.
Father’s age is 4 times more aged than his daughter, therefore father’s present age = y + 4y = 5y
After five years, father’s age will be three times his daughter age.
(4y + 5) = 3 (y + 5)
y = 10
After 5 years it was (4y + 5), then after further 5 years, father’s age = (4y +10) and daughter’s age = (y + 10)
(4y + 10) / (y + 10) = ?
Substituting the value of y, we get
[(4x10) + 10] / [10+10] = 5/2 = 2.5
After another 5 years, father will be 2.5 times of daughter's age.

The sum of present ages of Ashok, Anil and Ajay is 75 years.If 5 years ago the ratio of their ages was 3 : 4 : 5, What is the present age of Anil?

A. 26 Years
B. 25 Yearscorrect
C. 32 Years
D. 65 Years

Answer : B

Explanation:
Let 5 years age, the age of ashok, Anil and Ajay were 3x, 4x and 5x years. Then, their present ages are ( 3x + 5), (4x + 5) abd ( 5x + 5) years.
Now, 3x +5 + 4x +5 + 5x + 5 = 75 => 12x = 60 x = 5
Hence, present age of Anil = 4x + 5 = 4 x 5 + 5 = 25 years.

Ten years ago A was half of B in age. If the ratio of their present ages is 3: 4, what will be the total of their present ages?

A. 30
B. 35correct
C. 37
D. 41

Answer : B

Explanation:
Let A's age 10 years ago = x years.
Then, B's age 10 years ago = 2x years.
(x + 10) / (2x+ lO) = 3/4
=> x = 5.
So, the total of their present ages =(x + 10 + 2x + 10)
= (3x + 20) = 35 years.

Ten years ago, the age of mother was three times the age of her son. After ten years, mother’s age will be twice that of his son. Find the ratio of their present ages.

A. 11 : 7
B. 9 : 5
C. 7 : 4
D. 7 : 3

Answer : D

Explanation:
10 years ago, age of mother was three times the age of her son. Say, the age of son was x and mother's age was 3x.
At present: Mother's age is (3x + 10) and son’s age is (x + 10)
After ten years: Mother's age will be (3x + 10) +10 and son’s age will be (x + 10) + 10. Given that, mother’s age is twice that of son after ten years.
(3x + 10) +10 = 2 [(x + 10) + 10]
(3x + 20) = 2[x + 20]
Solving the equation, we get x = 20
(3x + 10): (x + 10) = 70: 30 = 7: 3.

The sum of the present ages of a father and his son is 60 years. five years ago, father's age was four times the age of the son. so now the son's age will be:

A. 5
B. 10
C. 15
D. 20

Answer: C

Explanation:
Let the present ages of son and father be x and (60 -x) years respectively.
Then, (60 - x) - 5= 4(x - 5)
55 - x = 4x - 20
5x = 75 => x = 15

Raj's age is 4 times that of Dhiraj, his cousin. 3 years back, Raj was 5 times as old as Dhiraj. What is his present age?

A. 12 years
B. 16 years
C. 24 years
D. 48 years

Answer : D

Explanation:
Present day,
Let us consider Dhiraj's present age as K years
Raj's present age is 4 times Dhiraj's = 4K years
3 years ago,
Dhiraj's age = K-3 years
Raj's age = 4K-3 years.
That time, Raj's age = 5 times Dhiraj's age
4K-3 = 5(K-3)
4K-3 = 5K-15
K = 12 years
Present age of Raj = 4K = 4 x 12 = 48 years.

Ray writes a two digit number. He sees that the number exceeds 4 times the sum of its digits by 3. If the number is increased by 18, the result is the same as the number formed by reversing the digits. Find the number.

a) 35
b) 42
c) 49
d) 57

Answer : Option A

Solution: Let the two digit number be xy.
4(x + y) +3 = 10x + y .......(1)
10x + y + 18 = 10 y + x ....(2)
Solving 1st equation we get 2x - y = 1 .....(3)
Solving 2nd equation we get y - x = 2 .....(4)
Solving 3 and 4, we get x = 3 and y = 5

A b c are non negitive integers such that 28a+30b+31c = 365. a + b + c = ?

a. Greater than 14
b. less than or equal to 11
c. 13
d. 12

ANSWER : D

In a calender,
Number of months having 28 days = 1
Number of months having 30 days = 4
Number of months having 31 days = 7
28 x 1 + 30 x 4 + 31 x 7 = 365
Here, a = 1, b = 4, c = 7.
a+b+c = 12

George can do a piece of work in 8 hours. Paul can do the same work in 10 hours, Hari can do the same work in 12 hours. George, Paul and Hari start the same work at 9 am, while George stops at 11 am, the remaining two complete the work. Approximately at what time will the work complete?

a. 11.30 am
b. 12 noon
c. 12.30 pm
d. 1 pm

ANSWER : D

Let the total work = 120 units.
As George completes this entire work in 8 hours, his capacity is 15 units /hour
Similarly, the capacity of paul is 12 units / hour
the capacity of Hari is 10 units / hour
All 3 started at 9 am and worked upto 11 am. So total work done upto 11 am = 2 x (15 + 12 + 10) = 74
Remaining work = 120 - 74 = 46
Now this work is to be done by paul and hari. 46 / (12 + 10) = 2 hours (approx)
So work gets completed at 1 pm

If x^y denotes x raised to the power y, Find last two digits of (1141^3843) + (1961^4181)

b) 82
c) 42
d) 22

ANSWER: B

J can dig a well in 16 days. P can dig a well in 24 days. J, P, H dig in 8 days. H alone can dig the well in How many days?

a) 32
b) 48
c) 96
d) 24

ANSWER: B

Assume the total work = 48 units.
Capacity fo J = 48 / 16 = 3 units / day
Capacity of P = 48 / 24 = 2 units / day
Capacity of J, P, H = 48 / 8 = 6 units / day
From the above capacity of H = 6 - 2 - 3 = 1
So H takes 48 / 1 days = 48 days to dig the well

3 mangoes and 4 apples costs Rs.85. 5 apples and 6 peaches costs 122. 6 mangoes and 2 peaches costs Rs.144. What is the combined price of 1 apple, 1 peach, and 1 mango.

a) 37
b) 39
c) 35
d) 36

Sol: Note: It is 114 not 144.
3m + 4a = 85 ..(1)
5a + 6p = 122 ..(2)
6m + 2p = 114 ..(3)
(1) x 2 => 6m + 8a = 170
(3) => 6m + 2p = 114
Solving we get 8a - 2p = 56 ..(4)
(2) => 5a + 6p = 122
3 x (4) = 24a - 6p = 168
Solving we get a = 10, p = 12, m = 15
So a + p + m = 37

At the end of 1994, R was half as old as his grandmother. The sum of the years in which they were born is 3844. How old R was at the end of 1999

a) 48
b) 55
c) 49
d) 53
In 1994, Assume the ages of GM and R = 2k, k
then their birth years are 1994 - 2k, 1994 - k.
But given that sum of these years is 3844.
So 1994 - 2k + 1994 - k = 3844
K = 48
In 1999, the age of R is 48 + 5 = 53
