SSC CHSL 2024 PYQ — Question 61

The correct answer is option 4 i.e.  $28\frac{4}{7}$ %.

Expenditure = Price × Consumption

Let the original price be ₹100

So, the new price = ₹140

Let Original Consumption = 1 unit

Here, 100 × 1 = 140 × New Consumption

⇒ New Consumption = 100/140 = 5/7

Decrease in Consumption = 1 - (5/7) = 2/7

Percentage decrease = (2/7) × 100 = $28\frac{4}{7}$%

Therefore, the consumption of tea should be decreased by $28\frac{4}{7}$%.
