Question

11+13=8 and 12+14=15 then find 16+17=?

Answer 1

Answer:

56

Step-by-step explanation:

11 + 13 = (1+1) +(1+3) = 2*4 = 8

12+ 14 = (1+2) +(1+4) = 3*5 =15

16+ 17 = (1+6) +(1+7) = 7*8 = 56

Answer 2

Answer:

In the given series 16 + 17 = 56

Step-by-step explanation:

11 + 13 = 8

12 + 14 = 15

its understand from the series that the equations are just product of sum of the digits to derive the sum at RHS

11 + 13 = 8

ie (1 + 1) x (1+3) = 2 x 4 = 8

12 + 14 = 15

ie (1 + 2) x (1 + 4) = 3 x 5 = 15

Therefore 16 + 17 =

(1 + 6) x (1+7) = 7 x 8 = 56
