Question

the price of one dozen egg was rupees 60 in August and the price of half dozen eggs was rupees 37.50 in the September in a particular year calculate the percentage increase in the price of eggs in one month

Answer 1

$\tt{\huge{ANSWER:}}$

Given:

1 dozen egg = Rs. 60
1 dozen = 12 eggs

Thus, cost of 1 egg = $\frac{60}{12}$
=》 Rs. 5

Next, we're given that:

Half dozen egg = Rs. 37.5
Half dozen = 6 eggs

Thus, cost of 1 egg = $\frac{37.5}{6}$
=》 Rs. 6.25

Increase = Cost after increase - Cost before increase

=》 Rs. (6.25 - 5)

=》 $\textbf{Increase = Rs. 1.25}$

Increase % = $\frac{Increase}{Cost\:\:before\:\:increase}\times 100$

=》 $\frac{1.25}{5}\times100$

=》 $\textbf{25}$%

Hope it Helps! :)

Answer 2

Hello!

First of all we have to find the price of eggs in August

Therefore, 1 dozen eggs =60

we know that 1 dozen = 12

------------------------------------------

                      August

Therefore, 60/12 = 5

5 rs is the cost of one egg!

----------------------------------------

                              September

Half dozen eggs in september = 37.5

1 Dozen = 12

Therefore, Half dozen = 12/2 = 6

----------------------------------------

Now, we have to divide Half dozen eggs with 6 eggs

                     = 37.5/6

                     = 6.25

==============================

In this question the eggs are increased, that's why we have to use formula of increase.

             Increase = Cost price before increase - Cost price after increase

                               = (6.25-5) = 1.25

---------------------------------------------------------------

Now, we have to find increase %

Increase % = Cost before increase/ Increase * 100

                   = 1.25/5 * 100

                    = 1.25/5 = 0.25

                   = 0.25*100

                   = 25%

-------------------------------------------------

Hence, the percentage increase in the price of eggs in one month is 25%

--------------------------------------------

                               Answer: 25%
