Test: Profit & Loss - Class 5 MCQ

Least Cost Price = Rs. (200 * 8) = Rs. 1600.
Greatest Selling Price = Rs. (425 * 8) = Rs. 3400.
Required profit = Rs. (3400 - 1600) = Rs. 1800.

So we have C.P. = 27.50
S.P. = 28.60
Gain = 28.60 - 27.50 = Rs. 1.10
Gain%=(GainCost*100)%=(1.1027.50*100)%=4%

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
20 - x x 100 = 25
x
2000 - 100x = 25x
125x = 2000
x = 16.

We know, C.P. = 5000
S.P. = 4000
Loss = 5000 - 4000 = 1000
Loss%=(LossCost*100)%=(10005000*100)%=20%

Let the new S.P. be x, then.
(100 - loss%):(1st S.P.) = (100 + gain%):(2nd S.P.)
=>(951140=105x)=>x=1260

Whenever we get this type of question, we should have formula in mind that,
Gain% = (gain/cost)*100
Cost = 4700 + 800 = Rs. 5500
S.P. = Rs. 5800
Profit = 5800 - 5500 = 300

Let the S.P = 100
then C.P. = 25
Profit = 75
Profit% = 75/25 * 100 = 300 %

Let the Cost Price of one article = Rs. 1
CP of x articles = Rs. x
CP of 20 articles = 20
Selling price of x articles = 20
Profit = 25% [Given]

Please note in this type of questions, get the value of 1 kg to solve this question, lets solve it.
C.P. of 1 Kg = 420/70 = Rs. 6
Selling Price = 6.50
Gain = Rs. 0.50
