The price of an electronic watch is first reduced by 25% and then increased by 50%. If the resulting price of the electronic watch is ₹7,650, then what was its original price (in ₹)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6,800.
Given that, final price of watch = ₹7,650
The price is first decreased by 25% and then increased by 50%.
Let the original price of watch be x.
According to the given question,
x × 75% × 150% = 7650
⇒ x × 3 × 3 = 7650 × 4 × 2
⇒ x = 850 × 8
⇒ x = 6800
