In each of the following questions, some equations are solved on the basis of certain system. Find out the correct answer for the unsolved equation on that basis.
`2 xx 4 xx 6 = 4, 9 xx 3 xx 7 = 13, 4 xx 7 xx 6 = 3, 9 xx 7 xx 8 = ?`

A

10

B

`09`

C

`08`

D

`07`

Text Solution

Verified by Experts

The correct Answer is:
A
`2 xx 4 xx 6 = 4`
`implies 6 - 4 = 2 , 2 + 2 = 4`
Third Number - Second Number + First Number = Result
`9 xx 3 xx 7 =13`
`implies 7 - 3 + 9 = 16 - 3 = 13`
`4 xx 7 xx 6 = 3`
`implies 6 - 7 + 4 = 3`
`implies 10 - 7 = 3`
`9 xx 7 xx 8`
`implies 8 - 7 + 9`
`implies 17 - 7 = 10`.
