In each of the following questons , which one of the four interchanges in signs and numbers would make the given equation correct /true ?
` (7 div 3) xx 5 =6`

A

C

No interchange, 5 and 7

D

`div` to` -, 3 and 5`

Text Solution

Verified by Experts

The correct Answer is:
D
Changing `.div " and .-.` and interchanging 3 and 5 in the given equation, we get `( 7 -5) xx 3 =6`
Using BODMAS RULE, we get
` 2 xx 3 = 6`
or, 6=6, which is correct.
