Answer 2

Given:

In the following questions, some equations are solved on the basis of a certain system.

To Find:

Find the correct answer for the unsolved  equation on that basis of:

If 228 = 12 and 337 = 16, then 569 = ?

(A) 39

(B) 20

(C) 29

(D) 36​

Solution:

From the given set of examples, we can say that digital sum is done in both cases.
