(A) 11 only

(B) 7 only

(D) 13 only

Show Answer Discuss Share

Correct Answer - Option (C)

Explanation:
The number (x y z x y z) can be written, after giving corresponding weightage of the places at which the digits occur, as 100000 x + 10000y + 1000z + 100x + 10y + z = 100100x + 10010y + 1001z = 1001 (100x + 10y + z) Since 1001 is a factor, the number is divisible by 1001. 7 × 11 × 13 = 1001 As the number is divisible by 1001, it will also be divisible by all three namely, 7, 11 and 13 and not by only one of these because all three are factors of 1001. So, the answer is 1001.

5) In a division sum, the divisor is 10 times the quotient and 5 times the remainder. If the remainder is 46, then the dividend is

(A) 4306

7) Which of the following number is NOT divisible by 18 ?

(A) 50436

(B) 54036

(D) 34056

Show Answer Discuss Share

Correct Answer - Option (C)

Explanation:
A number will be exactly divisible by 18 if it is divisible by 2 and 9 both. Clearly 65043 is not divisible by 2. ∴ Required number = 65043

8) The sum of first sixty numbers from one to sixty is divisible by

(A) 59

(B) 13

(D) 60

Show Answer Discuss Share

Correct Answer - Option (C)

Explanation:
Sum of first 60 numbers = 60(60+1)/2 = 60×61/2 = 1830 The number 1830 is divisible by 61.

9) Two numbers, when divided by 17, leave remainders 13 and 11 respectively. If the sum of those two numbers is divided by 17, the remainder will be

(A) 11

(B) 13

(D) 7

10) When a number is divided by 24, the remainder is 16. The remainder when the same number is divided by 12 is

(A) 4

(B) 3

(D) 6
