Ravi purchased 20 dozens of toys at the rate of Rs. 375 per dozen. He sold each one of the rate of Rs. 33.

• Profit percentage P%

$\large\red{\underline{\underline{\bf{\blue{Solution}}}}}$

Now,

➟ Number of dozens = 20

➟ Cost of Each dozen = 375 Rs

Then,

➟ Cost of 20 dozen = 375 × 20 = 7500 Rs

➟ Selling Price of Each toy in a dozen = 33 Rs

➟ No of toys in 20 dozens = 20 × 12 = 240

Then,

➟ Selling Price of 20 dozens = 240 × 33 = 7920 Rs

We know that,

➦ Profit (P) = Selling Price - Cost Price

➟ P = 7920 - 7500

➟ P = 420

Now,

We also know that,

➦ Profit % = P/CP × 100

Here,

➦ CP = 7500

➦ P = 420

So,

➟ Profit % = 420/7500 × 100

➟ P% = 420/75 = 84/15 = 28/5

➟ P% = 5.6 %

Hence,

• Profit Percent P% = 5.6%

Answer 2

Answer:

Cost of 1 dozen toys = ₹ 375

cost of 20 dozen toys = cost of one dozen toys× 20

=} 375×20

=} 7500₹

He sold each toy at = 33₹

total no. of toys= 20 dozens= 240 toys

S.P of 240 toys= S.P of one toy× 240

=} 33*240

=} 7920₹

profit :- S.P-C.P

=} 7920-7500

=} 420₹
