Profit, Loss and Discount Questions
D
Correct answer
Explanation
Let CP of B = x, so CP of A = 2x. SP of A = 90% of 2x = 1.8x. SP of B = 7/5 of x = 1.4x. Difference: 1.8x - 1.4x = 0.4x = 1200, so x = 3000. CP of A = 2×3000 = 6000. Options A, B, C are miscalculations.

Rs. 15,000
C
Correct answer
Explanation
Let Sharma's cost price be x. He sells at 20% loss, so Kelkar buys it at 0.8x. Kelkar spends Rs. 2000 on repair, so his total cost is 0.8x + 2000. Kelkar sells at 10% profit: 22000 = 1.1 × (0.8x + 2000). So 0.8x + 2000 = 22000/1.1 = 20000. Therefore 0.8x = 18000, and x = 18000/0.8 = 22500. Sharma's cost price was Rs. 22,500.

D
Correct answer
Explanation
Let CP = x. Marked price = 1.4x. After 5% discount, SP = 1.4x × 0.95 = 1.33x = 1064. So x = 1064/1.33 = 800. Profit = 1064 - 800 = 264.

Rs. 2550
C
Correct answer
Explanation
After successive discounts of 10% and 5%, the final price is 90% × 95% = 85.5% of marked price. So marked price = 2052 ÷ 0.855 = Rs. 2400. Successive discounts multiply, not add.

B
Correct answer
Explanation
Let CP = c. First case: MP = 1.35c, SP after 20% discount = 1.35c × 0.8 = 1.08c. Second case: MP = 1.60c, SP after 25% discount = 1.60c × 0.75 = 1.20c. Difference in SP = 1.20c - 1.08c = 0.12c = 2040. So c = 2040/0.12 = 17000. First MP = 1.35 × 17000 = 22950. Common mistake: mixing up which MP to find.

B
Correct answer
Explanation
Company: CP=120, SP=140, Profit=20, Profit% = 20/120 × 100 = 16.67%. Dealer: CP=140, SP=170, Profit=30, Profit% = 30/140 × 100 = 21.43%. Shopkeeper: CP=170, SP=204, Profit=34, Profit% = 34/170 × 100 = 20%. Customer has no profit. Dealer's profit = 21 3/7% is highest.
E
Correct answer
Explanation
Let CP of each bag = x. First bag: SP = 1.3x. Second bag: SP = 1.3x + 1700. Total CP = 2x, Total SP = 2.6x + 1700. Net profit = 40%, so Total SP = 1.4 × 2x = 2.8x. So 2.8x = 2.6x + 1700, 0.2x = 1700, x = 8500. Each bag costs Rs 8500.
A
Correct answer
Explanation
After 15% discount, price becomes 3000 × 0.85 = 2550. After 'a'% discount, final price is 2142. So 2550 × (1 - a/100) = 2142, giving (1 - a/100) = 2142/2550 = 0.84. Therefore a/100 = 0.16, so a = 16%.

$125\%$
-
$150\%$
C
Correct answer
Explanation
Let CP = 100, Profit = 20, so SP = 120. Given profit = 4 × discount. Let discount = d, then 20 = 4d, so d = 5. This means MP - 5 = 120, so MP = 125. Therefore MP is 125% of CP. Option A (25%) is incorrect, B (120%) would mean MP = SP, and D (150%) doesn't satisfy the condition.

A
Correct answer
Explanation
The shopkeeper wants a 10% profit after giving 12.5% discount. Cost = Rs. 1470. Selling price for 10% profit = 1470 × 1.10 = 1617. This selling price is after 12.5% discount on marked price, so 1617 = MP × (1 - 0.125) = MP × 0.875. Therefore, Marked Price = 1617/0.875 = 1848. Alternatively: MP = 1470 × 1.10/0.875 = 1848.
D
Correct answer
Explanation
SP = (8/7)CP. Profit = SP - CP = (8/7)CP - CP = (1/7)CP. Profit% = (Profit/CP) × 100 = (1/7) × 100 = 100/7%.

5 % gain
D
Correct answer
Explanation
First find CP: SP = 2070, profit = 15%, so CP = 2070/1.15 = 1800. New SP = 1890. Profit = 1890 - 1800 = 90. Profit percent = (90/1800) × 100 = 5%. Therefore, there is a 5% gain when sold at Rs. 1890. The key is to first establish the cost price from the first selling price, then calculate profit/loss on the new price.

D
Correct answer
Explanation
First article CP = 6500/1.04 = Rs. 6250. Second article CP = Rs. 3750, SP at 4% loss = 3750 x 0.96 = Rs. 3600. Total CP = 6250 + 3750 = Rs. 10000, Total SP = 6500 + 3600 = Rs. 10100. Overall profit = Rs. 100 on Rs. 10000, which is 1% gain.

C
Correct answer
Explanation
Let CP1 be cost price of first fan, SP2 be selling price of second fan. Given CP1 = SP2. Let CP2 be cost price of second fan. First fan: SP1 = 0.7 CP1 (30% loss). Second fan: SP2 = 2 CP2 (100% gain). Total SP = 3400. So 0.7 CP1 + CP1 = 3400 (since CP1 = SP2). Thus 1.7 CP1 = 3400, CP1 = 2000. CP2 = CP1/2 = 1000 (since SP2 = 2 CP2). Total CP = 2000 + 1000 = 3000. Profit = 3400 - 3000 = 400.

A
Correct answer
Explanation
Let CP = x. MP = x + 0.28x = 1.28x. After 15% discount: 1.28x × 0.85 = 1.088x. After 20% discount: 1.088x × 0.80 = 0.8704x. Loss = CP - SP = x - 0.8704x = 0.1296x. Given loss = Rs. 1296, so 0.1296x = 1296, meaning x = 1296/0.1296 = 10000. SP = 0.8704 × 10000 = 8704. This matches option A.
