# A factory requires 42 machines to produce a given number of articles in 63 days.How many machines would be required to produce the same number of articles in54 days?

Answer :

The more the no of machines, the less days will be required to produce a given no of articles.

Therefore, the no of machines and no of days are in inverse proportion.

Hence,

42 × 63 = 54 × x { x be the no of machines required to produce a given no of articles in 54 days}

→x = 49
