After interchanging `-:` and `xx, 10` and 5 which one of the following becomes a correct equation ?

Options

A. `(30-:5)xx10=24`
B. `(30xx10)-:5=60`
C. `(3-:10)xx5=18`
D. `(10-:30)xx5=70`

Answer

B

Explanation

Option (1)
`(30+5)xx10=64`
`rArr (30xx10)-:5=24`
`rArr 300-:5=24`
Option (2)
`(30xx10)-:5=60`
`rArr (30-:5)xx10=60`
`rArr 6xx10=60`
Option (3)
`(30-:10)xx5=18`
`rArr (30xx5)-:10=18`
`rArr 150-:10=18`
`rArr 15 ne 18`
Option (4)
`(10-:30)+10=70`
`rArr 150-: 10=70`
`rArr 15 ne 70`
