Answer 1

Answer: The cost price for Hari is 840 RS,

The cost price for Ram is 800 Rs

Step-by-step explanation: We start by working back with the profit made by Hari which is given as RS 882. What this means is that after selling the camera Ram has RS 882 which is made up of the cost price plus the profit or we can denote this figure as 105%.

To compute the extra 5% on 882, we can write out the following expression

882/x = 105/100

Where 882 is the cost price plus the 5% profit and x is the cost price. Hence 882/x = 105/100

By cross multiplication we now have

882 × 100 = 105x

88200 = 105x

Divide both sides of the equation by 105

840 = x

The cost price for Hari is Rs 840. That means Ram sold it at RS 840 and made a 5% profit. We shall adopt a similar approach to calculate Ram's cost price, which is

840/y = 105/100

Where 840 is the cost price plus the 5% profit and y is the cost price

Hence 840/y = 105/100

By cross multiplication we now have

840 × 100 = 105y

84000 = 105y

Divide both sides of the equation by 105

800 = y

The cost price for Ram is Rs 800.
