Question

A dealer bought a number of eggs at rupees 18 per dozen and sell them at a profit of rupees 50% find the selling price for egg

Answer 1

=50\100×18
=9%
Selling price =18+9
selling price =27

Answer 2

Solution - Formula to calculate % profit = (sp - cp) * 100/ cp

Given - cp = Rs 18 per dozen
Therefor cp of one egg = 18/12 = Rs 1.5

% profit = 50% = (sp - 1.5) * 100 / 1.5

(50 * 1.5) / 100 = sp - 1.5

75/100 = sp - 1.5

sp - 1.5 = 0.75

sp = 0.75 + 1.5 = Rs 2.25

Answer - Selling price of an egg is Rs 2.25
