The Cooperative Bank of Kenya, one of Kenya’s largest banks, tweeted out this problem.

If 4 + 2 = 26

8 + 1 = 79

6 + 5 = 111

Then what is 7 + 3 = ?

What do you think the answer is ?

My challenge: if 7 + 3 = z, solve for another pair of numbers x + y = z. Very few can solve this challenge problem!

Get an explanation of the solution.
