Question

Sandhya sold a table for Rs. 900 and made a profit of 20%. How much did he buy the table for?​

Answer 1

• She buys the table of Rs.750 .

Step-by-step explanation:

Given:-

• Selling price is Rs.900 .
• Profit percent is 20%.

To find:-

• In how much rupees she buys the table or Cost price of table.

Solution:-

Profit = Selling price - Cost price

= 900 - Cost price

We know,

Profit percent = Profit/Cost price × 100

➞ 20 = 900 - C.P/C.P × 100 [C.P = Cost price]

➞ 20 × C.P = 900 - C.P × 100

➞ 20/100 × C.P = 900 - C.P

➞ C.P /5 = 900 - C.P

➞ C.P = 5×(900 - C.P)

➞ C.P = 4500 - 5C.P

➞ C.P + 5 C.P = 4500

➞ 6 C.P = 4500

➞ C.P = 4500/6

➞ C.P = 750

Cost price or price of table that she buys is Rs.750.

Therefore,

She buys the table of Rs.750
