Description : Dhuviksha sells his two camera one at 45% loss and another at 30% profit. If the cost prices of the two cameras are in the ratio of 1:2, what is his percent profit or loss?

Last Answer :  Given that CPs are in the ratio 1:2 Therefore let the CPs be Rs.100 &Rs. 200 respectively, 1st SP = 100-45% of 100 = Rs. 55. 2nd SP = 200 + 30% of 200 = Rs. 260. Total CP = Rs.300. ... + 260 = Rs.315. Profit = Rs.315-300 = Rs.15. Profit percent = 15*100/300 = 5% profit.

Description : By selling a marker for Rs.18, a boy loses one nineteenth of what it costs him. The cost of the marker is? 

Last Answer : Let us assume cost price is x Ie., x – 18=1/ 19*x X – 18=x/19 X –x/19= 18 18x=18*19 18x=342 X=342/18 X=19

Description : By selling a pen for Rs.15, a man loses one sixteenth of what it costs him. The cost of the pen is?

Last Answer : Let us assume cost price is x Ie., x – 15 =1/ 16x X – 15-x/16 X - x/16 = 15 16x - x/16 = 15 15x = 15/16 X = 15x16/15 X = 16.

A man purchased wheat worth Rs. 400. He sold 3/4 at a loss of 10% and the reminder at a gain of 10%. On the whole he gets: A. loss of 5% B. gain of 5 C. loss of 19% D. loss of 6%

Description : A man purchased wheat worth Rs. 400. He sold 3/4 at a loss of 10% and the reminder at a gain of 10%. On the whole he gets: A. loss of 5% B. gain of 5 C. loss of 19% D. loss of 6%

Last Answer : Answer – A (loss of 5%) Explanation – C.P of 3/4th = Rs. (3/4 x 400) = Rs. 300, C.P of 1/4th = Rs. 100 ∴ Total S.P = (90% of Rs. 300 + 110% of Rs. 100) = Rs. 380 Loss = (20/400 x 100)% = 5%

A man sells two flats for Rs. 8000 each. neither loosing nor gaining in the deal. If he sold one at a gain of 25%, the other commodity sold at a loss of: A. 50/3 % B. 18 /3% C. 25% D. 32%

Description : A man sells two flats for Rs. 8000 each. neither loosing nor gaining in the deal. If he sold one at a gain of 25%, the other commodity sold at a loss of: A. 50/3 % B. 18 /3% C. 25% D. 32%

Last Answer : Answer – A (50/3 %) Explanation – Total S.P = 16000 Rs. and Total C.P = 16000 Rs. S.P. of Ist = Rs. 8000. Gain on it = 25% C.P of Ist = Rs. (100/125 x 8000) = Rs.6400 C.P of 2nd = Rs, (16000 – 6400) = Rs. 9600. S.P of 2nd = 8000. ∴loss on 2nd commodity = (1600/9600 x 100)% = 50/3%

Every year before the Diwali festival, the kumaran stores increases the price of the product by 48% and then introduce two successive discount of 12% and 13% respectively. What is percentage loss and percentage gain ?

Description :  Every year before the Diwali festival, the kumaran stores increases the price of the product by 48% and then introduce two successive discount of 12% and 13% respectively. What is percentage loss and percentage gain ?

Last Answer : Let CP = 100,  48 % increase =>SP = 148 12 % discount in SP => ((148 x 12)/100) = 17.76 So 1st SP = (148 – 17.76) = 130.24  13 % discount in 1st SP ((130.24x13)/100) = 16.93 2nd SP = 130.24-16.93= 113.31 So finally CP = 100, SP = 113.31 => gain = 13.31%

Usha purchased 10 fans for Rs 1000 each. She spent Rs 4000 on the maintenance of all fans. She sold five of them for Rs 1500 each and the remaining for 1100 each. Then the total gain or loss % is?

Description : A substance is purchased for Rs. 300. If one fourth of the substance is sold at a loss of 10% and the remaining at a gain of 5%, Find out the overall gain or loss percentage.

Last Answer : Price Received by selling one fourth of the substance at a loss of 10% = (1/4) * 300 * (90/100) = Rs. 67.5 Price Received by remaining substance at a gain of 5% = (3/4) * 300 * (105/100) = Rs.236. ... 75 Profit = 303.75 - 300 = 3.75 Profit%=(Gain/Cost∗100)% =(3.75/300∗100)% =1.25%

Description : An product is sold at a loss of 10%. Had it been sold for Rs. 9 more, there would have been a gain of 12 1/2% on it. The cost price of the product is

Last Answer : Let the cost price of the product = Rs. x S.P. at 10% loss = x×90/100= Rs. 9x/10 S.P. at 12 1/2 % gain x × (100+12 1/2)/100 = Rs. 225x/200 9x/10 + 9 = 225x/200 180x + 1800 = 225x x = Rs. 40

Description : Murugan sold a book at a loss of 40%. If the selling price had been increased by Rs.200, there would have been a gain of 10%. What was the cost price of the book?

Last Answer : Let cost price be Rs ‘x’  Then (110% of x) – (60 % of x) = 200  (110x/100) - (60x/10) = 200  110x – 60x = 20000  X = 400  So cost price of the book = Rs.400

Description : A car worth Rs.2,50,000 is sold by usha to nandhini at 10 % profit. Nandhini sells the car back to usha at 4% loss. Then in the entire transaction total gain by usha is?

Last Answer : Money spent by usha = Rs.2,50,000  Money received by usha = 110% of Rs.2,50,000 = 2,75,000  Cost price to usha = 96% of Rs.2,75.000 = Rs.2,64,000  Therefore usha gains Rs(2,75,000 – 2,64,000) = Rs.11000
