43) Nitish sold his watch and sun glassesat a loss of 4% and gain of 4% respectively for 2600 to Kamal. Kamal sold the same sun glasses and watch at a loss of 4% and gain of 4% respectively for 2700. The price of watch and sun glasses to Nitish were.

Solution:
Let the CP of watch be Rs x and sunglasses be Rs y.
2600=96x/100 + 104y/100
2700= 104x/100 + 96y/100
On solving,
y=700
x=1960
