Question

Chetna went to the market and bought 1.5 kg of sugar for rs.25. how much would she have to pay for 500gm

Answer 1

1 kg = 1000 gm
Let, 1.5 kg = x gm
Cross multiplying,
So, x = 1.5 × 1000 = 1500 gm

Chetna pays 25 Rs for 1500 gm,
So, let her pay y Rs for 500 gm.
Cross multiplying,
y = (500 × 25)/ 1500
So, y = (1 × 25)/3
So, y = 8.33

So, Chetna will pay Rs 8 and 33 paise for 500 gm of sugar.
