Question

Five balls of equal weight can be made of 12kg 5gm of iron. How many such balls weigh 45 quintals ?​

Answer 1

Answer:

15 iron balls of same size weigh 10kg 50g how many of them will weigh 4kg 690g

The number of balls which will weigh 4 kg 690 g is 7.

Given, that the weight of 15 iron balls is 10kg 50g. To represent this weight in gms, we know 1 kg = 1000gm, so: 10kg 50 gm = (10×1000)+50 = 10000+50 = 10050gm. And, 4kg 690gm = (4×1000)+690 = 4690 gm.
