Question

What is the difference of the sum of (4p - q + 12) and (-q -11) from (3p - q - 11)?
1. -p - q -12
2. -p + q - 12
3. p + q + 16
4. -2p + q - 16

Answer 1

Correct Answer - Option 2 : -p + q - 12

Calculation:

Sum = (4p - q + 12) + (-q -11)

⇒ Sum = 4p - 2q + 1

Difference = (3p - q - 11) - (4p - 2q + 1)

⇒ Difference = (3p - q - 11 - 4p + 2q - 1)

⇒ Difference = (-p + q -12)

∴ The difference of the sum of (4p - q + 12) and (-q -11) from (3p - q - 11) is (-p + q -12)

The correct option is 2 i.e. (-p + q -12)
