Question

A shopkeeper buys pencils at rs10 for rs10 and sells them at 8 for rs 10.find the profit per cent.

Answer 1

C.P of 10 pencils = ₹10

C.P of 1 pencil = ₹10/10=₹1

S.P of 8 pencils =₹10

S.P of 1 pencil = 10/8 =₹1.25

Gain = 1.25-1= ₹0.25

Gain percent= (Gain/Cost price )×100= (0.25/1) ×100= 0.25×100

Gain %= 25%

Answer 2

Answer:

25%

Step-by-step explanation:

Given :A shopkeeper buys pencils at Rs.10 for Rs.10 and sells them at 8 for Rs 10.

To Find: Find the profit per cent.

Solution:

S.P. of 10 pencils = rs.10

S.P. of 1 pencil = Rs. 1

C.P. of 8 pencils = Rs. 10

C.P. of 1 pencil = $\frac{8}{10}=\frac{4}{5}=0.8$

Profit = S.P. - C.P. = 1- 0.8 =0.2

CP% = $\frac{Profit}{CP} \times 100$

CP% = $\frac{0.2}{0.8} \times 100$

CP% = $25\%$

Hence the profit 5 is 25%.
