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

Options

A. `50 xx 5 div 2 - 30 + 25 = 25`
B. `50 - 30 + 5 div 2 xx 30 = 25`
C. `40 + 35 xx 2 - 50 div 30 = 95`
D. `30 xx 2 - 25 + 50 div 5 = 100`

Answer

A

Explanation

Option (I)
`50 xx 5 div 2 - 30 + 25 = 25`
`implies 50 div 5 xx 2 + 30 - 25 = 25`
`implies 10 xx 2 + 30 - 25 = 25`
`implies 20 + 30 - 25 = 25`
Option (2)
`50 - 30 + 5 div 2 xx 30 = 25`
`implies 50 + 30 - 5 xx 2 div 30 = 25`
`implies 50 + 30 - 1/3 = 25`
`implies 80 - 1/3 != 25`
Option (3)
`40 + 35 xx 2 - 50 div 30 = 95`
`implies 40 - 35 div 2 + 50 xx 30 = 95`
`implies 40 - 35/2 + 1500 != 95`
Option (4)
`30 xx 2 - 25 + 50 div 5 = 100`
`implies 30 div 2 + 25 - 50 xx 5 = 100`
`implies 15 + 25 - 250 != 100`.
