Some equations are solved on the basis of a certain system. Find the correct answer for the unsolved equation on that basis.
`5 xx 8= 28,3 xx 7 = 12,8 xx 6 = 35, 13 xx 13 = ?`

A

169

B

130

C

140

D

144

Text Solution

Verified by Experts

The correct Answer is:
B
`5xx8=28`
`implies5xx8=40`
`implies5+8=13,13-1=12`
`implies40-12=28`
`3xx7=12`
`implies3xx7=21`
`implies3+7=10,10-1=9`
`implies21-9=12`
`8xx6=35`
`implies8xx6=48`
`implies8+6=14,14-1=13`
`implies48-13=35`
`13xx13=?`
`implies13xx13=169`
`implies13+13=26,26-1=25`
`implies169-25=144`
