SSC GD Constable 5 Feb 2025 Shift 2 Paper

Net percentage change $=($ Final Price - Initial Price $)∕$ Initial Price $\times 100$
Final Price $=$ Initial Price $\times (1+.$ Percentage Change ${}_1^{})\times (1+.$ Percentage Change ${}_2^{})\times (1+.$ Percentage Change ${}_3^{})$
Calculation:
Let the initial price of the shirt be 100.
After a 15\% increase:
⇒ New Price $=100\times \left(1+15∕100\right)$
⇒ New Price $=100\times 1.15=115$
After a $12\%$ decrease:
⇒ New Price $=115\times \left(1-12∕100\right)$
⇒ New Price $=115\times 0.88=101.2$
After an 8\% increase:
⇒ New Price $=101.2\times \left(1+8∕100\right)$
⇒ New Price $=101.2\times 1.08=109.296$
Net percentage change:
⇒ Net Change $=($ Final Price - Initial Price $)∕$ Initial Price $\times 100$
⇒ Net Change $=\left(109.296-100\right)∕100\times 100=9.296\%$
