Q.5 Find the whole quantity if

(a) 5% of it is 600

(b) 12 % of it is? 1080

(c) 40% of it is 500 km

(d) 70% of it is 14 minutes

(e) 8% of it is 40 litres

(a) 5% of it is 600

(b) 12 % of it is? 1080

(c) 40% of it is 500 km

(d) 70% of it is 14 minutes

(e) 8% of it is 40 litres

(a) 5% of x = 600 = \(\frac{5}{100} \)×x = 600

Or, x = \(\frac{600×100}{5} \) = 12000

(b) 12% of x = 1080 = \(\frac{12}{100} \) × x = 1080

Or, x = \(\frac{1080×100}{12} \) = 9000

(c) 40% of x =500 = \(\frac{40}{100} \) × x = 500

Or, x = \(\frac{500×100}{40} \) = 1250 km

(d) 70% of x = 14min = \(\frac{70}{100} \)×x = 14min

Or, x = \(\frac{14×100}{70} \) = 20

(e) 8% of x = 40 liters = \(\frac{8}{100} \)×x = 40 liters

Or, x = \(\frac{40×100}{8} \) = 500 litres
