A man sells TV sets at profit of 20%. How much total amount he gains in profit?
I. He sells 20 TV set.
II. He sells each TV set at Rs 12000.

Options
(1) If the question can be answered by using statement I alone but cannot be answered by statement II alone.
(2) If the question can be answered by using statement II alone but cannot be answered by statement I alone.
(3) If both statements I and II together are required to answer the question.
(4) If the answer can be found by using any of the two statements alone.
(5) If both the statements together are not sufficient to answer the question.

• (3) Both the statements I and II together are required to answer the question.
  
  Here total amount of gain is asked
  From statement I, number of TV set sold=20 is known required to find total selling price and
  From statement II, selling price of each TV set=12000 is known
  
  So by selling 20 TV set @ 12000 each, total selling price=20*12000=240000 Rs.
  As he earns 20% profit, so his cost price=240000*100/120=200000
  So amount he gains in profit=240000 -200000=40000 Rs.
  
  Hence both the statements are required to find out total amount of gain.
