### Question 2

Price of sugar is increased by 80%. By what percentage should consumption be reduced so that the expenditure remains same?

**A**

$44{4/9}$ %.

**B**

$51{1/8}$ %.

**C**

$35{6/11}$ %.

**D**

$38{9/11}$ %.

**Soln.**

**Ans: a**

Let price be Rs. 100/kg and the consumption be 1 kg. The current expenditure is 100 × 1 = Rs. 100. The new price of sugar is 100 + 80 = Rs. 180/kg. Let the new consumption be c kg. Now, if expenditure is to be same we should have 100 = 180 × c, which gives c = 100/180, so the decrease is 1 - $100/180$ = ${180 - 100}/180$ × 100% = ${400/9}$, which is same as: $44{4/9}$%.
