Question

If the cost price of 10 tubes is equal to the selling price of 5 tubes, find the profit percentage in this transaction.
1. 30%
2. 100%
3. 65%
4. 50%

Answer 1

Correct Answer - Option 2 : 100%

Given:

C.P of 10 tubes = S.P of 5 tubes 

Formula used:

Profit percentage = (Profit/C.P) × 100

Calculation:

10 C.P = 5 S.P

⇒ C.P/S.P = 1/2

Profit = S.P - C.P

Profit = 2 - 1 = 1 unit

Profit percentage = (Profit/C.P) × 100

⇒ (1/1) × 100 = 100%
