Question

The price of sugar increased by 20%. But expenses

increased only by 10%. What is the percentage increase

or decrease in consumption ?​

Answer 1

Answer:

8.33 % decrase in consumption

Step-by-step explanation:

Let say consumption = C  kg

Price  Per kg  =  P  Rs

Total Expense = CP

Price increased by 20 %

=> increased Price = P  + (20/100)P  = 1.2P

Expense Increased  by 10 %

Expense = CP + (10/100)CP = 1.1CP

Consumption = 1.1CP/1.2P  =  11C/12

Consumption decreased by C - 11C/12  =  C/12

% decrease in consuption = ((C/12)/C ) * 100  = 8.33 %
