Profit and loss

Ramesh bought flowers from a wholesaler for `10 per kg.

He made garlands from the flowers and sold them in the village
weekly market for `15 per kg.
Therefore, cost price = `10, selling price = `15.

Š The price at which an article (item) is bought is called the
cost price (CP).
Š The price at which an article or item is sold is called the selling price (SP).

Fast Check
(a) Anu buys a pencil-box for `85 and sells it for `90.

CP = ______ SP = ______
(b) Chhaya sold a ribbon at `63, which she had bought for `55.

CP = ______ SP = ______

(c) A shopkeeper sells cups at `180 per dozen, which he buys at `150 per dozen.
CP = ______ SP = ______

Here, we have three possibilities:
( i) SP > CP (ii) SP < CP (iii) SP = CP

Š When the selling price (SP) is greater than the cost price (CP), that is, SP > CP, then
there will be a profit.
Profit = SP – CP

Š When the selling price (SP) is less than the cost price (CP), that is, SP < CP, then
there will be a loss.

Loss = CP – SP
Š When the selling price (SP) is equal to the cost price (CP), that is, SP = CP, then there
will be neither a profit nor a loss.

Since the selling price (SP) of the flowers is greater than the cost price (CP) for Ramesh,
he gets a profit.

Example 1: A shopkeeper buys a toy car at `280 and sells it at `300. Does he gain a profit
or incur a loss? Find his profit or loss.
Solution: CP of a toy car = `280
SP of a toy car = `300
Here, SP > CP, that is `300 > `280.

Hence, the shopkeeper earns a profit.
Profit = SP – CP = `300 – `280 = `20
Thus, the shopkeeper gains a profit of `20.
