If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit? 1. 30% Answer & Explanation Answer:- 2 Explanation :- Let us suppose CP= Rs. 100. 3. A vendor bought toffees at 6 for a rupee. How many for a rupee must he sell to gain 20%? 1. 3 Answer & Explanation Answer:- 3 Explanation :- Let’s suppose CP of 6 toffees = Re. 1 SP of 6 toffees=120% of 1=6/5 4. On selling 17 balls at Rs. 720, there is a loss equal to the cost price of 5 balls. The cost price of a ball is: 1. Rs. 45 Answer & Explanation Answer:- 4 Explanation :- CP(17 Balls)-SP(17 balls)=CP(5 Balls) 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 Answer & Explanation Answer:- 2 Explanation :- CP(56 kg rice) = Rs. (26 x 20 + 30 x 36) => Rs. (520 + 1080)
S.P. = Rs. 5800.
Profit= S.P.- C.P. = Rs.(5800 – 5500) = Rs. 300.
Profit %age=(300*5500)/100
Profit %age=(6/11)%
2. 70%
3. 100%
4. 250%
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%
2. 4
3. 5
4. 6
for Rs 6/5 Toffees sold=6
For Rs 1,Toffees Sold=6*5/6=5
2. Rs. 50
3. Rs. 55
4. Rs. 60
CP(12 Balls)=SP(17 Balls)=Rs 720
CP(1 Ball)=720/12=60
2. 5%
3. 8%
4. 10%
5. None of these
=> Rs. 1600.
SP(56 kg rice) = Rs. (56 x 30)
=> Rs. 1680.
Profit=1680-1600=80
Profit percent=(80/1680)*100=5%
