Question

I am a 2-digit number. The sum of my digits is 11. I am divisible by both 4 and 7

Answer 1

It's 56

Explanation:

• We have 2 digit number

• the sum of digits is 11 and it is divisible by 4 and 7

• so, first possibility is 4×7=28 ; but the sum of digits is 11; so,the sum of digits is 2+8=10 which does not satisfies the first constraint

• next possible 2 digit number is 56: since the sum of digits is 5+6=11, 56 ÷ 7 = 8 , 56 ÷ 4 = 9

Answer 2

56 or 84
