In each equation decide which one of the following five equations under each would be correct by interchanging the signs and number as given.
`-, div and +, 18 and 8`

A

`(40 div 18) + 8 = 50`

B

`(18 - 18) div 1 =0`

C

`(14 xx 18) - 8 = 14`

D

`(32 - 18) xx 8 = 64`

Text Solution

Verified by Experts

The correct Answer is:
B
Interchanging symbols .-. and `.div.,` numbers .18. and .8. in option (b) statement, we have the new equatior as :
`( 8div 8) -1 =0`
Using BODMAS RULE, we get
`1-1 =0`
or, 0=0, which is correct.
