यदि `8 " ""*"" "9" "#" "3 = 51 " तथा " 12" ""*"" "6" "#" "4 = 72` हो , तो `13" ""*"" "11" "#" "6 = ?`

Options

A. 156
B. 128
C. 136
D. 144

Answer

D

Explanation

`8" ""*"" "9 " "#" "3 = 51`
`rArr (8+9) xx 3 = 51`
`rArr 17 xx 3 = 51`
`["*" rArr + , # rArr xx]`
`12" ""*"" "6" "#" "4 = 72`
`rArr (12 + 6) xx 4 = 72`
`rArr 18 xx 4 = 72`
अतः ,
`13" ""*"" "11" "#" "6 = ?`
`rArr ? = (13 +11) xx 6`
`rArr ? = 24 xx 6 = 144`
