Options

A. `16xx5-:10+4-3=19`
B. `16+5-:10xx4-3=9`
C. `16+5-10xx4-:3=9`
D. `16-5xx10-:4+3=12`

Answer

C

Explanation

Option (1)
`16xx5-:10+4-3=19`
`implies16+5-10xx4-:3=19`
`implies16+5-(10xx4)/(3)=19`
`implies21-(40)/(3)=19`
`implies(63-40)/(3)=19`
`implies(23)/(3)ne19`
Option (2)
`16+5-:10xx4-3=9`
`implies16xx5-10+4-:3=9`
`implies80-10+(4)/(3)=9`
`implies(240-30+4)/(3)=9`
`implies(214)/(3)ne9`
Option (3)
`16+5-10xx4-:3=9`
`implies16xx5-:10+4-3=9`
`implies8+4-3=9`
Option (4)
`16-5xx10-:4+3=12`
`implies16-:5+10-4xx3=12`
`implies(16)/(5)+10-12=12`
`implies(16+50-60)/(5)=12`
`implies(66-60)/(5)ne12`
