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

Options

A. `36 xx 4- 12 + 5 div 3 = 420`
B. `52 div 4 + 5 xx 8 - 2 = 36`
C. `36 -12 xx 6 div 3 + 4 = 60`
D. `43 xx 7 div 5 + 4 - 8 = 25`

Answer

B

Explanation

Option (1)
`36 xx 4- 12 + 5 + 3 = 420`
`rArr 36 + 4 + 12 xx 5 - 3 = 420`
`rArr 36 + 4/12 xx 5 -3 = 420`
`rArr 36 + 5/3 -3 = 420`
`rArr (108 + 5-9)/(3) = 420`
`rArr (104)/(3) ne 420`
Option (2) `52+4 + 5 xx 8-2 = 36`
`rArr 52 -4 xx 5 + 8 + 2 =36`
`rArr 52 - 20 + 4 = 36`
`rArr 56 - 20 = 36`
Option (3)
`36 - 12 xx 6 + 3 + 4 = 60`
`rArr 36 + 12 + 6-3 + 4 = 60 `
`rArr 3 + 6 - 12 ne 60`
Option (4)
`43 xx 7 + 5 + 4 -8 = 25`
` rArr 43 + 7 -5 xx 4 div 8 =25`
`rArr 43 + 7 - 5/2 = 25`
`rArr 50- 5/2 ne 25`
