The pulse rate of a person is 15 beats in 10 seconds. At this rate, what will be pulse rate of the person per minute?

A. Data insufficient

B. 100 beats per minute

C. 90 beats per minute

D. 150 beats per minute

The average of 7 numbers is 60. The average of the first three numbers is 50, while the average of the last three is 70. What must be the remaining number ?

A. 75

B. 60

C. 65

D. 55

Answer : B. 60

Explanation:

The sum of all the seven numbers = 60 * 7 = 420
The sum of the first three = 50 * 3 = 150
The sum of the last three = 70 * 3 = 210
Remaining Number = 420 – (210 + 150) = 60

If Shalu buys 6 more apples, his carton will weight 14.5 kilograms. If the weigh of one apple is 250 grams. How many apples did he initially had in his carton ?

A. 58

B. 56

C. 54

D. 52

Answer : D. 52

Explanation:

Weight of 1 apple = 250 g
Weight of 6 apples = 250 * 6 = 1.5 kg
Initial weight = 14.5 – 1.5 = 13 kg
Number of apples in his carton initially :
= 13000/250
= 52 apples

The total number of two-digit positive integer lesser than 100, which are not divisible by 2, 3 and 5 is ?

A. 23

B. 24

C. 25

D. 26

Answer : B. 24

Explanation:

Numbers less than 100 divisible by 2 are 10, 12, 14, 16,…,98.
Total numbers divisible by 2 are 45
Remaining numbers are 11, 13, 15, 17, 19…99 = 45

Numbers divisible by 3 in the above numbers are 15, 21, 27, 33, 39, 45, 51, 57, 63, 69, 75, 81, 87, 93 and 99.
Total numbers divisible by 3 are = 15
Remaining integers = 45-15 = 30.

Numbers divisible by 5 in the remaining numbers = 25, 35, 55, 65, 85, 95
Total numbers = 6
Remaining 30-6 = 24.

So 24 numbers are not divisible by 2, 3 and 5.

A and B are two number when divided by 7 leaves a remainder 3 and 5. What will be the remainder when A-B is divided by 7 ?

A. 4

B. 5

C. 6

D. 7

Answer : B. 5

Explanation:

A = 7x + 3,
B = 7y + 5
A – B = 7(x – y) – 2
A – B = 7(x – y) – 7 + 7 – 2 [By adding -7 and +7] A – B = 7(x – y – 1) + 5
As seen above, if we divide A-B by 7, the remainder will be 5.
