Question

A three digit number 3a⁵ is added to another 3 digit number 933 to give a 4 digit number 12b8, which is divisible by 11. Then find the value of a+b​

Answer 1

Step-by-step explanation:

3a5+933 =12b8

so we can write this,

12b8 - 933 = 3a5

its only true when a=0 and b=3

therefore, a+b = 3
