A

`xx,- + , div xx`

B

`div, div , xx, +, -`

C

`+, +, div , xx, -`

D

`div , +, div , - , xx`

Text Solution

Verified by Experts

The correct Answer is:
D

Using the mathametical signs given in (d), we get the given equation as `45 div 5 + 9 div 3 -2 xx 6 =0`
Using BODMAS RULE, we get
`9 + 3 -2 xx 6=0`
` or, 9 + 3 -12 =0`
` or, 12 - 12 =0`
`or, 0=0,` which is true
Therefore, the correct answer is (d)
