Answer:
selling price of computer is Rs 50,000
he gain 12%on computer
cost price of computer is Rs x
so,x+x.12/100=50,000
=> 112x=50,000×100
=> x=50,000×100/112
=> x=44642.86
again, selling price of laptop is 50,000
he losses 10% on laptop
cost price of laptop is rs y
so, y-y.10/100=50000
=> 90y=50000×100
=> y=50000×100/90
=> y=55,555.56
total cost price Rs(44642.86+55555.56)
=Rs 100198.42
total selling price Rs(50000+50000)
=Rs 100000
his overall profit is Rs(100198.42-100000)
=Rs 198.42
