यदि `7^(2) " "A" "7" "B" "9 = 16` तथा `5^(2)" "A" "5" "B" "7" "=12` हो , तो `9^(2)" "A" "3" "B" "8= ?`

Options

A. 17
B. 92
C. 86
D. 35

Answer

D

Explanation

`7^(2) " "A" "7" "B" "9 = 16`
`rArr (7xx7)/7 + 9 = 16`
`rArr 7 + 9 = 16`
`5^(2) " "A" "5" "B" "7 = 12`
`rArr (5xx5)/5 + 7 = 12`
`rArr 5 + 7 = 12`
अतः ,
`9^(2) " "A" "3" "B" "8 = ?`
` rArr ? = (9xx9)/3 + 8`
`rArr ? = 27 + 8 = 35`
