B. `50-30+5-:2xx30=25`
C. `40+35xx2-50-:30=95`
D. `30xx2-25+50-:5=100`

Answer

A

Explanation

Option (1)
`50xx5-:2-30+25=25`
`implies50-:5xx2+30-25=25`
`implies10xx2+30-25=25`
`implies20+30-25=25`
Option (2)
`50-30+5-:2xx30=25`
`implies50+30-5xx2-:30=25`
`implies50+30-(1)/(3)=25`
`implies80-(1)/(3)ne25`
Option (3)
`40+35xx2-50-:30=95`
`implies40-35-:2+50xx30=95`
`implies40-(35)/(2)+1500ne95`
Option (4) `30xx2-25+50-:5=100`
`implies30-:2+25-50xx5=100`
`implies15+25-250ne100`
