ICSE Class 8 Maths Selina Solutions Chapter 8 Profit Loss and Discount – Exercise 8 (A)
Megha bought 10 note-books for Rs.40 and sold them at Rs. 4.75 per note-book. Find, her gain percent.
C.P. of 10 note-books = Rs.40
S.P. of 10 Note-books @ Rs.4.75 per note book
Gain = S.P. – C.P.
= Rs.47.50 – Rs.40 = Rs.7.50
Question 2 .
A fruit-seller buys oranges at 4 for Rs. 3 and sells them at 3 for Rs.4. Find his profit percent.
Let number of oranges bought = 12
(Note: L.C.M. of 4 and 3 = 12)
∴ C.P. of oranges=Rs.
And S.P. of oranges
Profit = 16 – 9 = Rs.7
A man buys a certain number of articles at 15 for Rs. 112.50 and sells them at 12 for Rs. 108
(i) His gain a percent;
(ii) The number of articles sold to make a profit of Rs.75.
Let number of articles bought = 60
∵ L.C.M of 15 and 12= 60
∴ C.P. of the articles
and S.P. of the articles
(i) To find his gain as percent;
Gain = S.P – C.P. = Rs.540 – Rs.450 = Rs.90
(ii) To find the number of articles sold to make a profit of Rs.75.
To make a profit of Rs.90, the number of articles needed to be sold = 60
To make a profit of Re.1, the number of articles needed to be sold
To make a profit of Rs.75 the number of articles needed to be sold
A boy buys an old bicycle for Rs. 162 and spends Rs.18 on its repairs before selling the bicycles for Rs. 207. Find his gain or loss percent.
Buying price of the old bicycle = Rs.162
Money spent on repairs = Rs.18
Real C.P. of the bicycle = 162+18=Rs.180
S.P. of the bicycle = Rs.207
Profit= S.P. – C.P. = 207-162=Rs.45
An article is bought from Jaipur for Rs.4800 and is sold in Delhi for Rs. 5,820. If Rs. 1,200 is spent on its transportations, etc. find the loss or the gain as percent.
Cost price = Rs.4,800
Selling Price = Rs.5,820
Transport etc. charges = Rs.1,200
Total cost price = Rs 4800 + Rs. 1,200 = Rs. 6,000
Loss = Rs. 6000 – Rs.5820 = Rs. 180
Mohit sold a T.V. for Rs. 3,600; gaining one-sixth of its selling price. Find:
(i) The gain
(ii) The cost price of the TV.
(iii) The gain percent.
S.P. of T.V. = Rs.3,600
(i) To find the gain
Thus, gain = Rs.600
(ii) To find the cost price of the TV.
Cost price = S.P – gain = 3600 – 600 = Rs.3000
(iii) To find the gain percent.
By selling a certain number of goods for Rs. 5,500 a shopkeeper loses equal to one-tenth of their selling price. Find:
(i) The loss incurred
(ii) The cost price of the goods
(iii) The loss as percent.
S.P. = Rs. 5,500
(i) Loss incurred:
Loss incurred = Rs.550
(ii) Cost price:
C.P = Rs.5,500 + Rs.550 = Rs.6,050
(iii) Loss as percent:
The selling price of a sofa-set is
Let the cost price (C.P) = 1
The cost price of an article is 4/5 times of its selling price. Find the loss or the gain as percent.
Let S.P. = 1
Formula for finding the gain% is given below,
∴ Gain = Selling Price – Cost Price
I.e. Gain = S.P. – C.P.
A shopkeeper sells his goods at 80% of their cost price. Find the percent gain or loses.
Let C.P of good = Rs.100
∴ S.P. of goods
Loss = C.P – S.P = Rs.100 – Rs.80 = Rs.20
Formula for finding Loss%
The cost price of an article is 90% of its selling price. What is the profit or the loss as percent?
Let S.P of the article = Rs.100
∴ C.P. of the article
Gain = Rs.100 – Rs.90 = Rs.10
The cost price of an article is 30 percent less than its selling price. Find the profit or loss as percent.
Let S.P of the article = Rs.100
30% of S.P.
∴ C.P. of the article = 100 – 30 = Rs.70
Profit = S.P – C.P
Rs.100 – Rs.70 = Rs.30
A shop-keeper bought 300 eggs at 80 paisa each. 30 eggs were broken in transaction and then he sold the remaining eggs at one rupee each. Find his gain or loss as percent.
C.P. of 300 eggs at 80 paise each
No. of eggs which were broken in transaction = 30
Remaining eggs = 300 – 30 = 270
S.P. of eggs at Rs.1 each
Gain = S.P – C.P. = Rs.270 – Rs.240 = Rs.30
A man sold his bicycle for Rs. 405 losing one-tenth of its cost price, find:
(i) Its cc price;
(ii) The loss percent
(i) Let C.P. of the bicycle = Rs. x
S.P. = C.P. – Loss
But, we are given S.P. = Rs.405.
∴ C.P. =Rs.450
(ii) The loss percent.
A man sold a radio-set for Rs.250 and gained one-ninth of its cost price. Find;
(i) Its cost price;
(ii) The profit percent.
(i) Let C.P. of the radio –set = Rs. x
S . P .
But, we are given S.P. of the radio-set =Rs.250
∴ C.P. of the radio set =Rs225
(ii) The profit percent.
Profit = Rs.
