Question

The price of sugar has gone up by 40%. By what percent should a family reduce the consumption of sugar

Answer 1

Let the price of sugar be 100/- per kg and the family uses 1 kg sugar

40% increase= 140/- per kg

At 100/-rate 1 kg sugar was available

now at 140/- rate 1 kg sugar is available

Therefore at current rate 100/140kg is available by spending 100/-= 5/7kg

5/7 kg= 714gms

Therefore consumption reduction is 1000gms(1kg)-714gms=286 gms

Therefore % reduction= 286/1000*100=28.6%
