Options

A. `18 -: 6-7 -5 xx 2 = 20`
B. `18 + 6 -: 7 xx 5 - 2 = 18`
C. `18 xx 6 - 7 -:5-2= 16`
D. `18 + 6 -: 7 - 5 xx 2 = 22`

Answer

B

Explanation

Option (1)
`18 -: 6 - 7 + 5 xx 2 = 20`
After conversion
`18 xx 6 + 7 -: 5 -2 = 20`
or, `108 + 7/5 - 2 ne 20`
Option (2)
`18 + 6 -: 7 xx 5 - 2 = 18`
After conversion
`18 -: 6 xx 7 - 5 + 2 = 18`
or, `3xx 7 - 5 ++2 = 18`
or, `21 - 5 + 2 = 18`
or, `23 - 5 = 18`
or, 18 = 18
