The correct Answer is:
B
The given expression is `40 div 360 xx 24 - 4 + 18`
Using the symbols correctly as given in the above question, the above expression become
`40 + 360 div 24 xx 4 -18`
Usign BODMAS RULE, we get
`40 + 15 xx 4 - 18 = 40 + 60 - 18 = 100 - 18 = 82`
Therefore, the value of the given expression = 82.
`1 xx (3)/(2) gt 1 lt 5 gt 3 xx (1)/(2)`
`or, (3)/(2) gt 1 lt 5 gt (3)/(2),` which is correct .
