Options

A. ` 4 lt 2 + 5 + 8 xx 5`
B. `4 = 2 + 5 gt 8 xx 5`
C. `4 lt 2 gt 5 + 8 xx 5`
D. `4 gt 2 lt 5 + 8-5`

Answer

A

Explanation

Option (1)
`4 lt 2 + 5 + 8 xx 5`
`implies 4 xx 2 - 5 -8 = 5`
`implies 8 - 5-8 ne 5`
Option (2)
`4 = 2 + 5 gt 8 xx 5`
`implies 4 div 2 - 5 + 8 =5`
`implies 2 - 5 + 8 =5`
Option (3)
`4 lt 2 gt 2 5 + 8 xx 5`
`implies 4 xx 2 + 5 - 8 =5`
`implies 8 + 5 - 8 =5`
Option (4)
`4 gt 2 lt 5 + 8 -5`
`implies 4 + 2 xx 5 - 8 gt 5`
`implies 4 + 10 -8 gt 5`
`implies 14-8 gt 5`
`implies 6 gt 5`
