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 + (20% of 100) =
100 + 20 = Rs 120.
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 (20/120) x 100 = 100/6 = hence, the consumption of 16 2/3% of tea is to
16 2/3 %.
be decreased so that the expenditure remains the same
