Question

a grocer bought 480eggs at rupees 18per dozen.he sold them at a gain of 15%.find the selling price of 100eggs.

Answer 1

Solution - Formula to calculate % profit = (sp - cp) * 100/ cp
Given - cp = Rs 18 per dozenTherefor 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 100 egg = 2.25 ×100 = Rs.225
