15. Shahid works in a bank. He sits at the cash counter. Whenever there are too many coins he does not them. He just weighs them. Can you hold these coins and say which is the heaviest?

(1) How many coins are there in a sack of 5 rupees coins if it weigh:

(a) 18 kg?
Ans. (a) Since 1 kg = 1000 g. So, 18 kg = 18000 g.

(d) 2kg and 250g?
Ans. (d) 2 kg and 250 g = 2 x 1000g + 250 g = 2000 g + 250 g = 2250 g.
If one coin weighs 9g, then the sack weighing 2250 g has 2250/9 = 250 coins in it.

(e) 1 kg and 125 g?
Ans. 
(e) 1 kg and 125 g = 1 x 1000 g + 125 g = 1000 g + 125 g = 1125 g
If one coin weighs 9g, then the sack weighing 4500 g has 1125/9 = 125 coins in it.

(2) A 2 rupee coin weighs 6 g. What is the weight of a sack with:

(a) 2200 coins? ___ kg ____ g
Ans. (a) Weight of 2 rupee coins = 6 g
Weight of 2200 such coins = 2200 x 6 g = 13200 g = 13000 g + 200 g = 13 kg 200g

(b) 3000 coins? ____ kg
If 100 one rupee coins weigh 485 g then how much will 10000 coins weigh?
__ kg __ g.
Ans. (b) Weight of 2-rupee coins= 6 g
Weight of 3000 such coins =3000 6g = 18000 g = 18 x 1000 g = 18 kg
If 100 one-rupee coins weigh 485 g, then 10000 such coins weigh
= 485 x 100 g = 48500 g = 48 x 1000 g = 500 g = 48 kg 500 g
