Question
If the price of tea increases by 50%, what percent
should the consumption be cut down to keep the spending constant?Answer should be rounded off to the nearest integer.Solution
ATQ,
Initial price = Rs. 100m, consumption = n
Initial expenditure = 100mn
New price = 150m
New consumption = 100mn ÷ 150m = 100n ÷ 150
Decrease = n - (100n ÷ 150) = 50n ÷ 150
Required percent = (50n ÷ 150) ÷ n × 100 = 5000 ÷ 150 ≈ 33%
