Question

if s.p.=rs 210,profit percent=5%,c.p =rs x,find c.p.

Answer 1

• C.P is Rs. 200 .

Step-by-step explanation:

To find:-

• C.P

Solution:-

Given that,

S.P is Rs.210 .

Profit percent is 5%.

• Here, S.P is Selling price and C.P is cost price.

Profit = S.P - C.P

➝ 210 - C.P

Profit percent = Profit/C.P × 100

➝ 5 = (210 - C.P/C.P) × 100

➝ 5 × C.P = (210 - C.P) × 100

➝ 5/100 × C.P = 210 - C.P

➝ C.P/20 = 210 - C.P

➝ C.P = 20×(210 - C.P)

➝ C.P = 4200 - 20 C.P

➝ 20 C.P + C.P = 4200

➝ 21 C.P = 4200

➝ C.P = 4200/21

➝ C.P = 200

Therefore,

C.P is Rs.200 .
