Answer 1

Answer:

(i) ₹2000

(ii) ₹2800

(iii) ₹1420

(iv) ₹1725

(v) ₹2050

Explanation:

In case of gain:
SP = CP(1 + Gain%) ⇒ CP = SP/(1 + Gain%)
SP = CP + Gain ⇒ CP = SP - Gain

In case of loss:
SP = CP(1 - Loss%) ⇒ CP = SP/(1 - Loss%)
SP = CP - Loss ⇒ CP = SP + Loss

(i) CP = 2200/(1 + 10%) = 2200×100/110 = 200×10 = 2000

(ii) CP = 2520/(1 - 10%) = 2520×100/90 = 280×10 = 2800

(iii) CP = 1400 + 20 = 1420

(iv) CP = 1800 - 75 = 1725

(v) CP = 2460/(1 + 20%) = 2460×100/120 = 410×5 = 2050
