यदि `18 xx 12 = 206" तथा " 19 xx 22 = 408`, हो , तो `23 xx 36 = ?`

Options

A. 878
B. 818
C. 794
D. 776

Answer

B

Explanation

`18 xx 12 = 206`
`rArr 18 xx 12 - 10 = 206`
`rArr 216 -10 = 206`
`19 xx 22 = 408`
`rArr 19 xx 22 - 10 = 408`
`rArr 418 - 10 = 408`
अतः ,
`23 xx 36 = ?`
`rArr ? = 23 xx 36 - 10`
`rArr ? = 828 - 10 = 818`
