Question

Example 5. A dealer sold two machines at 3500
each. On selling one machine, he gained 20% and on
selling the other he lost 20%. Find his net gain or loss
per cent.​

Answer 1

Answer:

profit on 1st machine=20*3500/100

=700

sp=4200

loss on2nd machine=700

sp=2800

total cp= 7000

total sp= 7000

no loss and no profit because cp and sp are equal
