Step-by-step explanation:
Here :-
- Selling price of 10 mangoes is equal to the cost price of 12 mangoes
Let the cost price of one mango be ₹1. So :-
- Cost Price of 10 mangoes = ₹10
- Selling Price of 10 mangoes = ₹12
↝ Here the selling price of 10 mangoes is equal to the cost price of 12 mangoes. It means selling price of 10 mangoes = cost price of 12 mangoes. So, the selling price of 12 mangoes is ₹12 and the cost price of 10 mangoes is ₹10.
