An agent buys a T.V. set listed at Rs. 10000 and gets 10% and 20% successive discounts. He spends 10% of his C.P. on transport. At what price (in rupees) should he sell the T.V. set to earn a profit of 10%? Choose one.
A) 8692  B) 8702  C) 8712  D) 8722  E) None of these
Net price after two discounts=80% of 90% of Rs. 10000=Rs. 7200.   Net C.P.=(7200+10% of Rs. 7200)=7920.   Therefore, S.P. =110% of Rs. 7920=Rs. 8712.   ANSWER:8712
