A person buys 15 pens for ₹100, and sells them at 13 pens for ₹100. What is the gain percentage?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e.15 5/13 percent.
Calculations:
A person buys 15 pens for ₹100 = CP of 15 pens is ₹100 ---- (1)
Sells them at 13 pens for ₹100 = SP of 13 pens is ₹100 ---- (2)
Equating equal number of pens in both equation, multiply (1) by 13 and (2) by 15;
⇒ CP = 1300 (of 195 pens)
⇒ SP = 1500 (of 195 pens)
⇒ Profit = SP - CP
⇒ Profit = 1500 - 1300 = 200
Hence, required profit % = [Profit/CP] × 100
⇒ [200/1300] × 100
⇒ 15(5/13)%
