Question

If 7*2=10,14*7=84 and 8*6=36, then find the value of 9*8.

Answer 1

The value of 9*8 is "56".

Step-by-step explanation:

Given 7*2 = 10, 14*7= 84 and 8*6 = 36 and  9*8 = ?

The patter follow,

(Product of both numbers) - 2 × Second number.

7*2 = 7 × 2 - (2 × 2) = 14 - 10 = 4,

14*7 = 14 × 7 - (2 × 7) = 98 - 14 = 84,

8*6 = 8 × 6 - (2 × 6) = 48 - 12 = 36

∴ 9*8 = 9 × 8 - (2 × 8) = 72 - 16 = 56

Hence, the value of 9*8 is "56".
