Question

Christmas cards are bought at ₹ 1,500 per 100 and sold at ₹ 200 a dozen. Find the gain per cent​

Answer 1

ANSWER

11.11..%

Step-by-step explanation:

BEFORE SELLING

price of 100 cards = ₹1500

price of 1 card = ₹1500/100 = ₹15

AFTER SELLING

price of dozen (12) cards = ₹200

price of 1 card = ₹200/12 = ₹50/3

A card is purchased at ₹15 and sold at ₹50/3

Gain = SP - CP = ₹50/3 - ₹15 = ₹5/3

so gain percent will be = (GAIN/CP)×100

$= \frac{ \frac{5}{3} }{15} \times 100$

$= \frac{5}{45} \times 100$

$= \frac{100}{9}$

= 11.11..%
