Question

Ais a digit and 3A18 is a multiple of 6. Which of the following can be the valueof A? (a) 1 or9 (b) 3 or6 (c) 0 or7 (d) 0 or9

Answer 1

Answer:a)1 or 9 and b)3 or 6

Step-by-step explanation:

If we replace a by 1 we get, 3x1x18=54

54 divided by 6 is equal to 9-Divisible

If we replace a by 9 we get 3x9x18=486

486 divided by 6 is equal to 81-Divisible

Therefore, option A is proved to be correct

Looking at option b,

If we replace a by 3 we get, 3x3x18=162

162 divided by 6 is equal to 27-Divisible

If we replace a by 6 we get, 3x6x18=324

324 divided by 6 is equal to 54

Therefore, option B is proved to be correct

c and d are wrong because if we replace a by 0 we end up with zero which is not divisible by 6. Therefore option a and b are the right answers
