Answer 1

S O L U T I O N :

Given :

• Cost price, (C.P) = Rs.15000
• Profit = 20%
• Selling price = ?

Explanation :

As we know that formula of the Selling price when profit :

• Selling price = 100 + profit%/100 × C.P

According to the question :

➛ Selling price = 100 + gain% /100 × C.P

➛ Selling price = (100 + 20% /100)% × 15000

➛ Selling price = 100 + 20/100 × 15000

➛ Selling price = 120/100 × 15000

➛ Selling price = Rs.(120 × 150)

➛ Selling price = Rs.18000

Thus,

The selling price of an article will be Rs.18000 .

More formulas :

• S.P = 100 - loss% /100 × C.P
• C.P = 100/100 + profit% × S.P
• C.P = 100/100 - loss% × S.P

Answer 2

Solution. S.P. of the fan = Rs 649, profit = 18%

Therefore, Rs 649 = ( 1 + 18100) of C.P.

=> Rs 649 = 118100 of C.P.

=> C.P. = Rs (649 x 100118) = Rs 550

Hence the cost price of the fan = Rs 550.
