Answer: (2) Rs. 30, 000

Solution:-
Let the cost price of the T.V be Rs. X

Rekha earn Rs.900 more by selling a television with a profit of 7% instead of 4% profit.
Then, X x 7/100 – X x 4/100 = 900
(7 X – 4 X)/100 = 900
3 X = 900 x 100
X = 300 x 100
X  = Rs. 30, 000

Then, cost price of T.V. is Rs. 30, 000.

Hence, correct answer is option (2) Rs. 30, 000.
