| Most Important profit and loss questions and solution; asked in previous year competitive exam | |
| Q 1 | Ex. 1. A man bought a horse and a carriage for Rs. 3000. He sold the horse at a gain of 20% and the carriage at a loss of 10%, thereby gaining 2% on the whole. Find the cost of the horse. Q : एक आदमी ने 3000/- एक घोडा और एक गाड़ी खरीदी ; उसने घोडा 20% लाभ पर और गाड़ी 10% हानी पर बेच दी; जिससे उसे 2% का लाभ हुआ; घोड़े का क्रय मूल्य ज्ञात करो। |
| Solution | Let the C.P. of the horse be Rs. x. Then, C.P. of the carriage = Rs. (3000 — x). 20% of x — 10% of (3000 — x) = 2% of 3000 x/5 – (3000-x)/10 = 60 =2x—3000+x = 600 = 3x= 3600 x= 1200. Hence, C.P. of the horse = Rs. 1200. |
| Q 2 | Find the single discount equivalent to a series discount of 20%, 10% and 5%. Q:- एकल छूट ज्ञात करो जो लगातार 20%, 10% और 5% छूट के बराबर है। |
| Solution | Let marked price be Rs. 100. Then, Net S.P. = 95% of 90% of 80% of Rs. 100 = Rs(95/100 x90/100 x 80/100) x 100 = Rs. 68.40. … Required discount = (100 — 68.40)% = 31.6%. |
| Q 3 | After getting two successive discounts, a shirt with a list price of Rs. 150 available at Rs. 105. If the second discount is 12.5%, find the first discount. Q :- दो क्रमागत छूट के बाद एक कमीज़ के 105/- मे मिला जिसकी किमत 150/- थी। यदि दूसरी छूट 12.5% है तो दूसरी छूट ज्ञात करो। |
| Solution | Let the first discount be x%. Then, 87.5% of (100 — x)% of 150 = 105 87.5/100 x (100-x)/100 x 150 = 105 100-x = (105x100x100) / 150×87.5) =80 x = (100-80) = 20 First discount = 20% |
| Q 4 | An uneducated retailer marks all his goods at 50% above the cost price and thinking that he will still make 25% profit, offers a discount of 25% on the marked price. What is his actual profit on the sales? :- एक अनपड विक्रेता ने सभी वस्तुओ पर 50% बड़ा दिये क्रय मूल्य से। उसने सोचा की शायद उसने 25% ही बड़ाये जिससे उसने 25% छूट भी दे दी। उसका लाभ प्रतिशत ज्ञात करो। |
| Solution | Let C.P. = Rs. 100. Then, marked price = Rs. 150. S.P. = 75% of Rs. 150 = Rs. 112.50. … Gain% = 12.50%. |
| Q 5 | A retailer buys 40 pens at the marked price of 36 pens from a wholesaler If he sells these pens giving a discount of 1%, what is the profit percent? एक आदमी ने एक होलसेलर से 36 पेन की कीमत से 40 पेन खरीदे। अब उसने 1% छूट पर पेन बेचना शुरू किया , तो उसका लाभ ज्ञात करो। |
| Solution | Let the marked price of each pen be Re. 1. Then, C.P. of 40 pens = Rs. 36. S.P. of 40 pens = 99% of Rs. 40 = Rs. 39.60. Profit%= (3.60/36 x lOO) % = 10%. |
| Q6 | At what percentage above the C.P must an artide be marked so as to gain 33% after allowing a customer a discount of 5%? वह कीमत ज्ञात करो जिस पर उसे 33% का लाभ मिले जब वह उस वस्तु पर 10% के साथ छूट भी दे। |
| Solution | Let C.P. = Rs. 100. Then, S.P. =‘Rs. 133. Let marked price be Rs. x Then, 95% ofx= 133 95x/100=133 x = 133x 100/95J = 140 Marked price = 40% above C.P. |
