GIVEN

Due to an increase of 30%in the price of eggs , 3 eggs less are available for RS. 9.10

TO FIND

Percentage rate per egg

SOLUTION

The above problem can be simply solved as follows;

Let the original price per egg = x

Price per egg after 30% increase = x + 30% = x + 0.3 = 1.3x

Now,

(9.10/x) - (9.10/1.3x) = 3

(11.83- 9.10x)/1.3x² = 3

11.83 - 9.10x = 3.9x²

Rearranging the terms

3.9x² + 9.10x - 11.83 = 0

On solving

x = Rs 0.92

Present price = 1.3x = 1.3 × 0.92 = Rs 1.196

Hence, The answer is Rs 1.196
