This question is based on the five, three-digit numbers given below.

(Left) 324 523 643 136 441 (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?

Given: (Left) 324 523 643 136 441 (Right)

If 3 is added to the first digit of every number.

324 → (3 + 3) = 6 → 624

523 → (5 + 3) = 8 → 823

643 → (6 + 3) = 9 → 943

136 → (1 + 3) = 4 → 436

441 → (4 + 3) = 7 → 741

Divisibility of new first digit by second digit.

624 → 6 ÷ 2 = 3 (Yes)

823 → 8 ÷ 2 = 4 (Yes)

943 → 9 ÷ 4 = 2.25 (No)

436 → 4 ÷ 3 = 1.33 (No)

741 → 7 ÷ 4 = 1.75 (No)

Only 2 numbers (624, 823) satisfy the condition.

So, 2 numbers will the first digit be exactly divisible by the second digit.

Thus, correct option is (d).
