Correct Answer - Option 2 : 4 kg

**Given:**

The total consumption of sugar was 20 kg per month for a family.

the price of sugar increased by 35% and the expenditure on sugar is increased only by 8%

**Concept:**

Consumption × Price = Expenditure

Increment/Decrement in percentage = {(100 ± increase/decrease)/100} × Value

**Solution:**

Let the Price of sugar be Rs. 100 per kg

So, Initial expenditure is

⇒ 20 × 100 = Rs. 2000

The increased price of the sugar per kg is

⇒ (135/100) × 100 = Rs. 135

The increased Expenditure is

⇒ (108/100) × 2000

⇒ 2160

Now,

⇒ Consumption = Expenditure/Price

⇒ Consumption = 2160/135

⇒ Consumption = 16

Reduction in consumption is 20 - 16 = 4 kg

**∴ the consumption of sugar per month reduced is 4 kg.**
