Here are the Explanation of the Questions

(1)
:The sum of three consecutive odd numbers is always divisible by
I. 2 II. 3 III. 5 IV. 6

A) Only I
B) Only II
C) Only I and II
D) Only II and IV

The correct answer is: B
Explanation
(Let the three consecutive odd numbers be (2x+1), (2x+3) and (2x+5
Their sum = (6x=9)= 3 (2x+3), which is always divisible by 3

(2)
:The least number which must be subtracted from 6709 to make it exactly divisible by 9 is
A) 2
B) 3
C) 4
D) 5

The correct answer is: C
Explanation
On dividing 6709 by 9, we get remainder= 4
Therefore, required number to be subtracted= 4

(3)
:The least number by which 72 must be multiplied in order to produce a multiple of 112, is
a. 6
B) 12
C) 14
D) 18

The correct answer is: C
Explanation
Required number is divisible by 72 as well as by 112, if it is divisible by their LCM, which is 1008
Now, 1008 when divided by 72, gives quotient= 14
Therefore, required number= 14

(4)
:On dividing a number by 999, the quotient is 366 and the remainder is 103. The number is
A) 364724
B) 365387
C) 365737
D) 366757

The correct answer is: C
Explanation
Required number= 999*366+103= (1000-1)*366+103= 366000-366+103= 365737

(5)
?When a number is divided by 31, the remainder is 29. When the same number is divided by 16, what will be the remainder
A) 11
B) 13
C) 15
D) Data inadequate

The correct answer is: D
Explanation
Number= (31 * Q)+ 29. Given data is inadequate
