Find out the two signs to be interchanged for making the following equation correct :
`5 + 3 xx 8 - 12 div 4 = 3`

Options

A. `+ and -`
B. `+ and xx`
C. `- and div`
D. `xx and div`

Answer

D

Explanation

Interchanging Symbols `.xx. and .div.` in the given equation, we get `6 ^(2) div 2 ^(2) xx (3 ^(2) - 2 ^(2)) + 5 ^(2) = 70`
`or, 36 div 4 xx (9-4) + 25 = 70`
Using BODMAS RULE, we get
`36 div 4 xx 5 + 25 = 70`
`or, 9 xx 5 + 25 = 70`
`or, 45 + 25 = 70`
`or, 70=70` which is true
