Options

A. `4xx5+9-3-:4=15`
B. `4-5xx9+3-:4=32`
C. `4-5-:18xx3-4=70`
D. `4-:5+9-3-:4=81`

Answer

B

Explanation

Option (1)
`4xx5+9-3-:4=15`
`implies4+5xx9-:3-4=15`
`implies4+15-4=15`
Option (2)
`4-5xx9+3-:4=32`
`implies4-:5+9xx3-4=32`
`implies(4)/(5)+27-4=32`
`implies(4+135-20)/(5)=32`
`implies139-20=32xx5`
`implies119ne160`
Option (3)
`4-5-:18xx3-4=70`
`implies(4)/(5)-18+(3)/(4)=70`
`implies(16-360+15)/(20)=70`
`implies31-360=70xx20`
`implies-329ne1400`
Option (4)
`4-:5+9-3-:4=81`
`implies4-5xx9-:3-4=81`
`implies4-15-4=81`
`implies4-19=81`
`implies-15ne81`
