Ans 1: (Master Answer)
Class : Class 1
(B): Cost of 1 kg rice = ₹ 15
Cost of 10 kg rice = ₹ (15 × 10) = ₹ 150
Cost of 1 kg sugar = ₹ 20
Cost of 15.04 kg sugar = ₹ (20 × 15.04)
= ₹ 300.80
Cost of 1 kg salt = ₹ 9
Cost of 5.06 kg salt = ₹ (9 × 5.06) = ₹ 45.54
Total cost = ₹ (150 + 300.80 + 45.54) = ₹ 496.34
Amount of money Chinmay gave to shopkeeper
= ₹ 1000
∴ Amount of money he get back
= ₹ (1000 - 496.34) = ₹ 503.66
