Given :

A trader purchases a watch and a wall clock for 390 rupees. He sell them making a profit of 10 % on the watch and 15% on the wall clock. He earns a profit of 51.50 rupees.

To find :

What is the difference between the original prices of the wall clock and the watch is equal to.

Calculations :

→ x/10 + 15 (390 - x)/100 = 51.50

→ 10x + 5850 - 15x = 5150

→ 5x = 700

→ 700/5x

→ 140

Let's, substitute the above equation :

→ 390 - 140

→ 250

Therefore, the cost of the clock is equal to 250.

→ 250 - 140

→ 110

Therefore, 110 is difference between the original price of the wall clock.
