Question

Cost price ranges from 300 to 700.if it is sold for 650 the profit is twice the loss if it is sold for 350.what is the cost price

Answer 1

Step-by-step explanation:

forget about the range, let's assume the cost price = x

if it is sold for 350/-

then the cost price = x, sold price = 350/-

loss = cost price - sold price = x - 350

twice of loss = 2 * ( x - 350 )

it will be the profit for the first case.

for the first case,

the cost price = x, sold price = 650

profit = sold price - cost price = 650 - x

so, the established equation will be,

650 - x = 2 * ( x - 350 )

=> 650 - x = 2x - 700

=> 3x = 1350

=> x = 450

so, the cost price will be 450/-
