Question

This question is based on the five, three-digit numbers given below.
(Left) 248, 382, 425, 127, 335 (Right)
( Example -697- First digit =6, second digit =9 and third digit =7)
NOTE - All operations to be done from left to right.
If 3 is added to the first digit of every number, in how many numbers will the first digit be exactly divisible by the second digit?

A.

2

B.

4

C.

1

D.

3

Correct option is A

Given: (Left) 248, 382, 425, 127, 335 (Right)
Logic : (First digit +3) ÷\div (second digit) = divisible 
Solution:
For each number,
  1.  248 : (2+3) ÷\div 4 = 54\frac{5}{4} = completely not divisible
  2. 382 : (3+3) ÷\div8 = 68\frac{6}{8} = completely not divisible
  3. 425 : (4+3) ÷\div = 72\frac{7}{2} = completely not divisible
  4. 127 : (1+3) ÷\div2 = 42\frac{4}{2} =2 = completely divisible
  5. 335 : (3+3)  completely divisible÷\div 3 = 63=2\frac{6}{3}= 2 = completely divisible
Thus, there are 2 numbers where the first digit is exactly divisible by the second digit.
The correct answer is option ( a ) 2
