On selling a television at a 6% profit and a fridge at a 9% profit, a shopkeeper gains ₹5,100. However, if the shopkeeper sells the television at a 99% profit and the fridge at a 6% loss, he gains 1,800 on the whole transaction. The cost price (in ₹) of the fridge is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 30,000.
CP of TV = T and CP of Fridge = F
0.06T + 0.09F = 5100
⇒ 0.09T + 0.135F = 7650 .....(1)
Also, 0.09T - 0.06F = 1800 .....(2)
(1) - (2) ⇒ 0.195F = 5850
⇒ F = 5850/0.195 = 30000
