Question

If 2000 five-rupee coins weigh 18 kg, how many five-rupee coins will weigh 1 kg 125 g?

• A. 9
• B. 1125
• C. 125
• D. 90

Answer 1

The correct option is C 125

Weight of 2000 coins = 18 kg

We know that 1 kg = 1000 g

So, the weight of 2000 coins
= 18 x 1000
= 18000 g

Weight of 2000 coins = 18000 g
Weight of 1 coin = 18000 ÷ 2000
= 9 g

Now, 1 kg 125 g = 1 x 1000 + 125
= 1125 g

Number of five-rupee coins in 1125 g
= 1125 ÷ 9
= 125
