अगर (-) का मतलब `(div), (+)` का मतलब `(xx), (div)` का मतलब (-), `(xx)` का मतलब (+) हो, तो सही समीकरण ज्ञात कीजिए।

Options

A. `20-4+6-:9xx4=25`
B. `20+6-4xx9-:6=32`
C. `20-:9xx9-4+6=33`
D. `20xx4-6-4+9=20`

Answer

A

Explanation

Option (1)
`20-4+6-:9xx4=25`
`implies20-:4xx6-9+4=25`
`implies5xx6-9+4=25`
`implies30-9+4=25`
Opion (2)
`20+6-4xx9-:6=32`
`implies20xx6-:4+9-6=32`
`implies30+9-6ne32`
Option (3) `20-:9xx9-4+6=33`
`implies20-9+(9)/(4)xx6=33`
`implies20-9+(27)/(2)=33`
`implies(40-18+27)/(2)=33`
`implies49ne2xx33`
Option (4)
`20xx4-6-4+9=20`
`implies20+4-:6-:4xx9=20`
`implies20+(4)/(6)xx(1)/(4)xx9=20`
`implies20+(3)/(2)ne20`
