Question

2
The price of a computer was decreased by 30% to £336. What was the price before the decrease?

Answer 1

Answer :-

Let the price before decrease be x

According to the question :-

→ $\sf x - x\times 30\% = 336$

→ $\sf x - \dfrac{30x}{100} = 330$

→ $\sf 100x - 30x = 336 \times 100$

→ $\sf 70x = 33600$

→ $\sf x = \dfrac{33600}{70}$

→ $\boxed{\sf x = 480}$

∴ Price before decrease was £ 336.
