the price of mobile set is fixed 20% above its cost price when it is sold allowing 10% discount there is gain of rupees 440 find the mic price of mobile set​



Answer :

Answer:

Let the cost price of the mobile set be Rs X

Then, Selling price of mobile set is 20% above the cost price = 120% of X = Rs (120/100)X = 1.2X

The discount given is 10%

Selling price after discount = 80% of Rs 1.2X

= (80/100)1.2X = 0.96X

Now we have selling price after discount = 0.96X

Gain = Rs 440

So, 0.96X - X = 44
