Solution
The correct option is C 2000
We know, 1 kg = 1000 g
∴ Weight of 20 kg in grams = 20 × 1000 = 20000 g
Weight of a ₹ 5 coin = 10 g
Number of ₹ 5 coins in the bag
= 20000 ÷ 10 = 2000 coins
We know, 1 kg = 1000 g
∴ Weight of 20 kg in grams = 20 × 1000 = 20000 g
Weight of a ₹ 5 coin = 10 g
Number of ₹ 5 coins in the bag
= 20000 ÷ 10 = 2000 coins
