Answer 1

Correct Question :

If the Cost price of 15 Mobiles be equal to the Selling price of 18 Mobiles, Find Gain or Loss Percentage ?

Solution :

Given :

• Cost Price of 15 Mobiles = Selling Price of 18 Mobiles

To find :

• Gain or Loss Percentage

According to the question :

Let the Cost price of 1 Mobile be ' Rs. 1 ' ......(1)

∴ 15 Mobiles = 15 × 1 = 15

Selling Price of 1 Mobile = 15 / 18 ......(2)

Finding Loss :

⟹ Loss = Cost Price - Selling Price

⟹ Loss = 1 - 15 / 18

∴ Loss = 1 / 6

Finding Loss Percentage :

⟹ Loss % = Loss / Cost price × 100

⟹ Loss % = ( 1 / 6 ) / 1 × 100

⟹ Loss % = ( 1 / 6 × 1 / 1 ) × 100

⟹ Loss % = ( 1 / 6 ) × 100

⟹ Loss % = 50 / 3

∴ Loss % = 16 2 / 3 %

So Its Done !!
