1. Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:

1. 32/7%

2. 60/11%

3. 10%

4. 12%

Answer & Explanation

Answer:- 2

Explanation :-

C.P. = Rs. (4700 + 800) = Rs. 5500.

S.P. = Rs. 5800.

Profit= S.P.- C.P. = Rs.(5800 – 5500) = Rs. 300.

Profit %age=(300*5500)/100

Profit %age=(6/11)%

2. In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?

1. 30%

2. 70%

3. 100%

4. 250%

Answer & Explanation

Answer:- 2

Explanation :-

Let us suppose CP= Rs. 100.

Therefore ,

Profit = Rs. 320

SP = Rs. 420.

New CP = 125% of Rs. 100 = Rs. 125

New SP = Rs. 420.

New Profit = Rs. (420 – 125) = Rs. 295.

New profit %age= (295/420)*100

profit %age= 70%

5. A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. His profit percent is:

1. No profit, no loss

2. 5%

3. 8%

4. 10%

5. None of these

Answer & Explanation

Answer:- 2

Explanation :-

CP(56 kg rice) = Rs. (26 x 20 + 30 x 36)

=> Rs. (520 + 1080)

=> Rs. 1600.

SP(56 kg rice) = Rs. (56 x 30)

=> Rs. 1680.

Profit=1680-1600=80

Profit percent=(80/1680)*100=5%
