If '-' stands for division' '+' stands for multiplication', `'-:'` stands for subtraction `'xx'` stands for addition', then which one of the following equations is correct ?

Options

A. `36xx4-12+5-:3=420`
B. `52-:4+5xx8-2=36`
C. `36-12xx6-:3+4=60`
D. `43xx7-:5+4-8=25`

Answer

B

Explanation

Option (1)
`36xx4-12+5+3=420`
`implies36+4+12xx5-3=420`
`implies36+(4)/(12)xx5-3=420`
`implies36+(5)/(3)-3=420`
`implies(108+5-9)/(3)=420`
`=(104)/(3)ne420`
Option (2)
`52-:4+5xx8-2=36`
`implies52-4xx5+8+2=36`
`implies52-4xx5+4=36`
`implies52-20+4=36`
`implies56-20=36`
Option (3)
`36-12xx6+3+4=60`
`implies36-:12+6-3xx4=60`
`implies3+6-12ne60`
Option (4)
`43xx7+5+4-8=25`
`implies43+7-5xx4+8=25`
`implies43+7-(5)/(2)=25`
`implies50-(5)/(2)ne25`
