Question

If SP = Rs.84, % gain = 20%, then CP = ?
1. Rs.60
2. Rs.65
3. Rs.70
4. Rs.75

Answer 1

Correct Answer - Option 3 : Rs.70

Given:

Selling price = 84

The gain% = 20%

Formula used:

\(G\%\ =\ {SP\ -\ CP \over CP}\times 100\)     (Where G = Gain, SP = Selling price and CP = Cost price)

Calculation:

Let us assume cost price is CP

⇒ \(20\ =\ {84\ -\ CP \over CP}\times 100\)

⇒ By solving 

⇒ CP = 70

∴ The required result will be 70.
