Question

The price of a shirt is first increased by 15% and then decreased by 12%, and again increased by 8%. Find the net increase or decrease percentage (correct to one decimal place) in the price of the shirt.

• A. Increase of 10.6%
• B. Increase of 9.3%
• C. Decrease of 10.6%
• D. Decrease of 9.3%

Answer 1

Answer:

B. Increase of 9.3%

Let the original price of the shirt be ₹100.

Increase by 15%

$100 \times \frac{115}{100} = 115$

Decrease by 12%

$115 \times \frac{88}{100} = 101.2$

Increase by 8%

$101.2 \times \frac{108}{100} = 109.296$

Final price = ₹109.296

Net increase:

$109.296 - 100 = 9.296\%$

Correct to one decimal place:

$\boxed{9.3\% \text{ increase}}$
