Profit and Loss- Aptitude Questions and Answers

CP = 180,Gain = 20%
SP = (120/100) * 180= 216

Let the Marked Price be x.
Then, 80% of x = 216
80x/100 = 216
x =216*100/80 =217

Thus, Marked Price is 270

CP = (80% of 90% of 40000) + (1200)
= (80/100)*(90/100)*40000 + (1200)
= (28800 + 1200)
= 30000
So, CP = 30000 and SP = 30000
therefore no gain no loss in the transaction.

Let marked price was X. then
X - 10% of X = 45000
0.9X = 45000
X = 45000/0.9
X = 50000

The marked price price was Rs. 50000

Let x be the cost price
selling price = [100 + gain%)/100]*x =108*x/100

if he had sold it at Rs 75 less, he would have lost 2% i.e.
108*x/100 - 75 = 98*x/100
108*x - 7500 = 98*x
10x = 7500

Cost price X= Rs 750

sp of 90 ball pens = rs 160 =20% loss
so, cp of 90 ball pens = 160*100 / (100-20) =rs 200
cp of 1 ball pen =200/90 =20/9

let X ball pens are sold to earn20% profit
then , cp of X ball pens = X*(20/9)
as given SP of X ball pens = rs 96 , 20% profit

hence X*(20/9)=96*100 / (100+20) = 80
X=80*(9/20) = 36

So, 36 ball pens should be sold for rs 96 to earn profit of 20%

cost price of wrist watch = 225 + 15 = 240
Selling price = 300
Profit = 300 - 240 = 60

Profit % = (profit/cost price) * 100% = (60/240) * 100 = 25%

Let first radio cp is X second radio cp is 1920-X
As is given ,
X*(100 + 20)/100=(1920-X)*(100 - 20/3)/100
120*X=(1920-X)*(280/3)
360*X=(1920-X)*280
640*X=1920*280
X=840

Hence,second radio cp is 1920-X = 1920-840 =1080
CP of both Radio = 840 and 1080

Let the cp of article is X
As is given 425 -X = X - 355
2*X = 780
X=390

Gain percentage=(18–16 / 16)*100 = (2/16)*100 = 25/2 %

Cost price =960*100 / (100-4) = 960*100 / 96 = 1000

cp of 70 liters of milk = 630
after added 5 liters of water,total solution= 70+5 = 75 liters

sp of 1 liter milk = 9
so, sp of 75 liter milk = 9*75 = 675

profit % =(675-630 / 630)*100 = (45/630)*100 =50/7 %

SP of first mobile= 2400 , Profit = 20%
CP = SP * 100/100+P% = 2400* 100/120 = 2000

SP of Second mobile= Rs.1000 ,Loss = 20%
CP = SP * 100/100−L% = 2400* 100/80 = 3000

So, Total SP = 4800; Total CP = 5000
As the CP is more than SP, he makes a Loss = CP - SP = 5000 - 4800 = 200

So, Loss Percent = Loss* 100/CP = 200* 100/5000 = 4%

Let cost price of each bed = Rs x

Acoording to question,
(x * 130/100) + (x* 130/100 - 5504) = 2x * 114/100
=> 260x - 550400 = 228x
=> 32x = 550400
x = 17200

Let, the CP of washing machine be x, and the CP of the chimney will be (57750 - x)

SP of washing machine = SP of Chimney
x* (100-24)/100 = (57750-x)*(100+34)/100
x* 76/100 = (57750-x)*134/100
76x = 134*57750 - 134*x
210x = 134*57750
x = 134*57750 / 210
x = 36850

CP of washing machine, x = 36850
CP of chimney = (57750 - 36850)
So, the cheaper item will be chimney = 20900

Let cost price = 100, Loss = 30%
SP = 70 (100-30) = 2/3 of original SP

So, Original SP = 70 * 3/2 = 105
Original Profit = 5
Percentage profit = 5%

Profit = SP - CP (if SP > CP)
Profit = 12 - 10 = 2 Rs
