Let the original price of the sugar be Rs 100.

The price of the sugar is increased by 20%. Increased price of the sugar

= 100 + (20% of 100)

= 100 + 20

= Rs 120.

Increase in price = 120 - 100 = Rs 20

Sugar of cost Rs 20 is to decreased out of the increased cost of Rs 120.

Percentage decrease = (20/120) x 100 = 100/6 = 16 2/3 %.

Hence, the consumption of 16 2/3% of sugar be decreased so that the expenditure on sugar remains the same

Answer 2

Answer:

Step-by-step explanation:

Let previous price be 100

Increase= 20% = 20

New price = 100 + 20 = 120

% of increase/new price = 20/120=16.66

So it should decrease by the same value i.e. 16.66%
