Question

If 20+15=46
64+13=691
12+18=?

Answer 1

Heya,

This is a tricky question,

So,

20+15=46

we know,

20+15=35

now 3+5=8

square of 8=64

reverse of the answer i.e 64 is 46.


64+13=691


We know,


64+13=77

now 7+7=14

square of 14=196

reverse of the answer i.e 196 is 691.

12+18=9


We know,

12 + 18=30

now 3 + 0=3

square of 3=9

reverse of the answer i.e 9 is 9 .

hence the answer is 9.

Answer 2

Acc to the question,

If 20+15=46

try to decode it: 2 + 0 + 1 + 5 = 8; $8^{2}$ = 64; reversing it we get 46.

64+13=691 similarly, 6 + 4 + 1 + 3 = 14; $14^{2}$ = 196; reversing it we get 691

12+18=?

Therefore, 1 + 2 + 1 + 8 = 12; $12^{2}$ = 144; reversing it we get 441(Ans)
