Answer:
⇒ Let the original price of the tea be Rs.100.
⇒ The price of the tea is increased by 20%.
⇒ Increased price of the tea = 100+(
100
20
)=100+20=Rs120.
⇒ Increase in price = 120−100=Rs.20
⇒ Tea of cost Rs.20 is to decreased out of the increased cost of Rs.120.
⇒ Percentage decrease =
120
20
×100=
3
50
%.
Hence, the consumption of
3
50
% of tea is to be decreased so that the expenditure on tea remains the same.
