If x litre of water is filled in a pot, it remains empty by y% of its capacity. find its capacity?
Answer & explanation
Correct answer: option 1
Let total capacity = z litre
ATQ,
⇒ z - x = z × y%
⇒ z - x = z\(\frac{y}{100}\)
⇒ z - \(\frac{zy}{100}\) = x
⇒ z [1 - \(\frac{y}{100}\)] = x
⇒ z [\(\frac{100\;-\;y}{100}\)] = x
⇒ z = \(\frac{100x}{100-y}\)
