Question

a vender bought 9sweets for ₹1. At what rate should he sell it to gain 80%?​

Answer 1

He should sell it for 1₹ 80 paise

Answer 2

Answer:

Cost of 9 sweets = ₹ 1 or 100 paise

Gain = 80%

Selling price = Gain + Cost price

= (80/100) × 100+ 100 paise

= 80 + 100 = 180 paise

So Selling price = 100 paise or ₹ 1.8
