Question

what's the answer for this​

Answer 1

In 1st column if we add all number 1 + 4 + 2 = 7

and then we multiply the answer with itself 7×7=49

similarly in second column 4 + 2 + 2 = 8 and if we multiply it with itself we gettt 64

Therefore in third column we need two same number so when we multiply both number we get 169 . and we know 13 × 13 =169

therefore 5 + 5 + 3 = 13

Therefore your answer is 5
