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

Correct option is D

Given:
First discount = 30%
Second discount = 20%
Final amount paid = Rs. 840
Formula Used:
For successive discounts d₁ and d₂, net price after discounts:
​$$\text{Net price} = \text{Original price} \times \left(1 - \frac{d_1}{100}\right) \times \left(1 - \frac{d_2}{100}\right)$$​​
Solution:
Let the original price be x. Then,
​$$840 = x \times \left(1 - \frac{30}{100}\right) \times \left(1 - \frac{20}{100}\right) \\\ \\840 = x \times \frac{70}{100} \times \frac{80}{100} = x \times \frac{56}{100} \\\ \\ x = \frac{840 \times 100}{56} = 1500 \\$$​​
The original bill amount of the food item is Rs. 1500.
