1.	A factory required 42 machines to produce a given number of articles in 56 days. How many machines would be required to produce the same number of articles in 48 days?
Answer» If there are more number of machines, less number of days required to produce the given articles. Therefore it’s inversely proportional. Let us consider the required of machines be x 42 × 56 = 48 × x x = (42 × 56) /48 = 49 ∴ 49 machines are required.

Answer»

If there are more number of machines, less number of days required to produce the given articles. Therefore it’s inversely proportional.

Let us consider the required of machines be x

42 × 56 = 48 × x

x = (42 × 56) /48 = 49

∴ 49 machines are required.
