Answer 1

Given:

Someone purchase egg for 100. On the way, 20% eggs break

To find:

How much  the percentage he should increase the cost for remaining eggs to get a net profit of 10%

Solution:

Let the cost price of an egg is ₹1

So the cost price of 100 egg will be ₹100

It is given in the question that the 20% egg is destroyed it means 20 egg destroyed

so, 80 eggs left

To gain 10% profit the selling price of all the eggs must be

• ₹100+₹10 = ₹110

The price of an egg is given by:

• ₹110/80
• ₹1.375

Hence the price is increased by ₹0.375 and that is 37.5% of the Cost price

So the price of the egg is increased by 37.5%
