Question 38

Ritu purchased $$2\ \frac{1}{2}$$ dozen eggs at the rate of Rs.20 per dozen. She found that 6 eggs were rotten. She sold the remaining eggs at the rate of Rs.22 per dozen. Then her profit or loss percent is:

Solution

$$2\frac{1}{2} dozens$$ = $$\frac{5}{2}\times12$$=30 eggs

12 eggs price$$\rightarrow$$ Rs.20
then 30 eggs price$$\rightarrow$$ Rs. 50
No. of rotten eggs=6
Remaining eggs=24

Selling price of 12 eggs = Rs.22
Selling price of 24 eggs=$$2\times22$$=Rs.44

Loss percentage=$$\frac{S.P.-C.P.}{C.P}\times100$$

=$$\frac{50-44}{50}\times100$$

=$$\frac{6}{50}\times100$$=12% loss
