The purchase price of machine = 36000

The cost for repair = 2400

Total cost = 38400  and sold price =42000

There for percentage of profit  

42000 x 100/38400

=> 109.37%

Answer 2

Cost of machine = 36000
Additional charges = 2400
Total Cost = 36000+2400 = 38400
gain = 42000-38400 = 3600
gain % = ( gain/cp ) * 100%
= (3600/36000) * 100% = 100% ans
