In the following questions some equations are solved on the basis of a certain system. On the same basis, find out the correct answer for the unsolved equation
`{:(85 + 25 = 50),(97 + 65 = 93),(72 + 94 = ?):}`

Options

A. 92
B. 50
C. 67
D. 60

Answer

B

Explanation

As,
`85 + 25 to 8 xx 5 + 2 xx 5 = 40 + 10 = 50` and
`97 + 65 to 9 xx 7 + 6 xx 5 = 63 + 30 = 93 ` Similarly
`72 + 94 to 7 xx 2 + 9 xx 4 = 14 + 36 = 50 `
