A and B are two cars travelling to a destination which is 360 kilometres away. A takes 4 hours to reach the destination. How much time will it take B to reach the destination if the speeds of A and B are in the ratio 9: 12 ?

A. 2.5 hrs

B. 3.5 hrs

C. 4.5 hrs

D. 3 hrs

Answer : D. 3 hrs

Explanation :

9x/12x = 9/12
Time = Distance / Speed
4 = 360/9x
so x = 10
12x = 120
Time taken by car b = 360/120 =3 hour

Consider the following quotients :
1) 368.39 divided by 17
2) 170.50 divided by 62
3) 875.65 divided by 83
Their correct sequence in decreasing order is :

A. 1, 3, 2

B. 2, 1, 3

C. 2, 3, 1

D. 3, 1, 2

Answer : A. 1, 3, 2

Explanation :

  • 36839/17 = 2167, Dividend contains 2 places of decimal.
    So, 368.39 / 17 = 21.67
  • 17050/62 = 275, Dividend contains 2 places of decimal.
    So, 70.50/62 = 2.75
  • 87565/83 = 1055, Dividend contains 2 places of decimal.
    So, 875.65/83 = 10.55

Since 21.67 > 10.55 > 2.75. The desired order is 1, 3, 2.

X is a 5 digit number when we subtract the sum of the digits form X, it becomes divisible by _____ ?

A. 5

B. 1

C. 9

D. 6

Answer : C. 9

Explanation:

Every multiple of 9 (9, 18, 27, 36, etc.) has the property that its digits will always add up to a multiple of 9.
For example, the number 4,968 is a multiple of 9 (552 × 9), and its digits add up to 27 (3 × 9).
Because of how the problem is stated, with four-digit numbers, the sum of the digits will always be 9 or 18 or 27.
Adding 1 + 8 or adding 2 + 7 (as specified in the problem) again gives 9.

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.

If the number 7×86038 is exactly divisible by 11, then the smallest whole number in place of x ?

A. 1

B. 2

C. 3

D. 4

Answer : C. 3

Explanation:

The given number = 7×86038
Sum of the odd places = 8 + 0 + 8 + 7 = 23
Sum of the even places = 3 + 6 + x
(Sum of the odd places) – (Sum of even places) = Number (exactly divisible by 11)
23 – (9 + x) = divisible by 11
14 – x = divisible by 11.
X must be 3, to make given number divisible by 11.

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.

A. 21

B. 30

C. 27

Answer : C. 27

Explanation:

Let us take three consecutive numbers which are divisible by 3 are, 3x, 3x + 3 and 3x + 6.
3x + (3x + 3) + (3x + 6) = 72
9x + 9 = 72

When the integer n is divided by 8, the remainder is 3. What is the remainder if 6n is divided by 8 ?

A. 0

B. 2

C. 1

D. 3

Answer : B. 2

Explanation:

When n is divided by 8, the remainder is 3 may be written as
n = 8 k + 3
Multiply all terms by 6
6 n = 6(8 k + 3) = 8(6k) + 18
Write 18 as 16 + 2 since 16 = 8 * 2.
= 8(6k) + 16 + 2
Factor 8 out.
= 8(6k + 2) + 2
The above indicates that if 6n is divided by 8, the remainder is 2. The answer is B.

Find the smallest 4 digit number which is divisible by 18, 24, 32 ?

A. 1216

B. 1512

C. 1152

D. 1680

Answer : C. 1152

Explanation:

LCM of 18, 24 and 32:
–> 18 = 2 x 3 x 3
–> 24 = 2 x 2 x 2 x 3
–> 32 = 2 x 2 x 2 x 2 x 2
LCM = 2 x 2 x 2 x 2 x 2 x 3 x 3 = 288.

The smallest four digit number that is divisible by 288:
288 x 3 = 864
288 x 4 = 1152

Since 288 is divisible by 18, 24 and 32, 1152 is also divisible by all these numbers. Therefore, 1152 is the smallest four digit number divisible by 18, 24 and 32.

A. 67

B. 85

C. 129

D. 87

Answer : B. 85

Explanation:

Since the numbers are co-prime, they contain only 1 as the common factor.
It is also given that two products have the middle number in common.
So, middle number = H.C.F. of 551 and 1073 = 29.
So, First number is = 551/29 = 19.
Third number = 1073/29 = 37
So sum of these numbers is = (19 + 29 + 37) = 85.

Six bells commence tolling together and toll at the intervals of 2, 4, 6, 8, 10, 12 seconds respectively. In 60 minutes how many times they will toll together ?

A. 16

B. 15

C. 31

D. 30

Answer : C. 31

Explanation:

LCM of 2 , 4 , 6 ,8 , 10 , 12 is 120 seconds, that’s 2 minutes.
Now 60 / 2 = 30
Adding one bell at the beginning it’ll be 30 + 1 = 31.

Find the greatest number which on dividing 1661 and 2045, leaves a remainder of 10 and 13 respectively ?

A. 91

B. 127

C. 137

D. 140

Answer : B . 127

Explanation:

In this type of question, we need to calculate the HCF, trick is,
HCF (1661 – 10) and (2045 -13)
= HCF (1651, 2032)
= 127

Which greatest possible length can be used to measure exactly 15 meter 75 cm, 11 meter 25 cm & 7 meter 65 cm ?

A. 45

B. 255

C. 55

D. 36

Answer : A. 45

Explanation:

The HCF for given length.
–> 15 meter 75 cm = 1575 cm.
–> 11 meter 25 cm = 1125 cm
–> 7 meter 65 cm = 765 cm.

1575 = 5 * 5 * 3 * 3 * 7
1125 = 5 * 5 * 5 * 3 * 3
765 = 5 * 3 * 3 * 17

HCF of 1575 , 1125 and 765 is 45.

A. 12

B. 45

C. 77

D. 34

Answer : C. 77

Explanation:

For any this type of question, remember
Product of two numbers = Product of their HCF and LCM
So Other number = 693 × 11 / 99
= 77
