Question
The combined cost price and marked price of Watch 'A'
amounts to Rs. 11,000, while for Watch 'B', the total is Rs. 13,400. Watch 'A' is marked 20% above its cost price, and Watch 'B' is marked 200% above its cost price. If both watches are sold with a 10% discount on their marked prices, what is the difference between their selling prices?Solution
ATQ, Let the cost price of watch 'A' be Rs. 'x' Therefore, marked price of watch 'A' = 1.20 × x = Rs. '1.2x' ATQ, 1.2x + x = 11000 Or, 2.2x = 11000 Or, x = (11000/2.2) = 5000 Marked price of watch 'A' = 1.2x = 1.2 × 5000 = Rs. 6,000 Selling price of watch 'A' = 0.9 × 6000 = Rs. 5,400 Similarly, selling price of watch 'B' = Rs. 9,045 Required difference = 9045 - 5400 = Rs. 3,645
