Asifchacha sold a toy at 5% profit. If the cost price of the toy is less by 20% and selling price is less by Rs. 34, then Asifchacha would make a 10% profit. Let us calculate the cost price of the toy.

Formula used.


Loss/profit percent = × 100%


Let the cost price be X


Then;


Selling price = X+ = =


If cost price is less by 20%


Then;


X – = =


And selling price is less by Rs. 34


– Rs. 34 =


Profit = Selling price – Cost price


= – = = =


Loss/profit percent = × 100%


10%= ×100%


=


16X = 50X – 6800


34X = 6800


X = = 200


∴ Cost price of toy is Rs. 200.
