Let the initial price and initial consumption of sugar be Rs. '100m' per kg and 'n' kg respectively.
Initial expenditure = 100m X n = Rs. '100mn'
New price = 1.32 X 100m = Rs. '132m'
New consumption = (100mn/132m) = (100n/132) kg
Decrease in consumption = n - (100n/132) = (32n/132) kg
Required percent = [(32n/132) ÷ n] X 100 = (3200/132) ~ 24%
