Options

A. `5+2-12-:6xx2=13`
B. `5+2-12xx6-:2=10`
C. `5-:2+12xx6-2=4`
D. `5-2+12xx6-:2=27`

Answer

B

Explanation

`5+2-12-:6xx2=13`
`implies5xx2+12-6-:2=13`
`implies10+12-3=13`
`implies22-3ne13`
Option (2)
`5+2-12xx6-:2=10`
`implies5xx2+12-:6-2=10`
`implies10+2-2=10`
Option (3)
`5-:2+12xx6-2=4`
`implies5-2xx12-:6+2=4`
`implies5-2xx12-:6+2=4`
`implies5-4+2=4`
`implies7-4ne4`
Option (4)
`5-2+12xx6-:2=27`
`implies5+2xx12-:6-2=27`
`implies5+2xx2-2=27`
`implies5+4-2ne27`
