Question

Two successive discounts of 30% and 20% was offered on food items. A man paid ₹840 for the food item. The bill amount of food item (in ₹) is:

• A. 2000
• B. 1200
• C. 1800
• D. 1500

Answer 1

Answer:

D. 1500

Let the original bill amount be ₹x.

Two successive discounts are given:
First discount = 30%
Second discount = 20

Step 1: Apply first discount (30%)

After 30% discount, price becomes:
$x \times (1 - 0.30) = 0.7x$

Step 2: Apply second discount (20%) on the reduced price

$0.7x \times (1 - 0.20) = 0.7x \times 0.8 = 0.56x$

So, the final price paid = 0.56x

Given:
$0.56x = 840$
$x = \frac{840}{0.56}$
x = 1500

Original bill amount = ₹1500
