A) Rs. 9, 000
B) Rs. 15,000
C) Rs. 18, 000
D) Rs. 21,000
Correct Answer: A
Solution :
Suppose their prices are 3x, 5x and 7x. Then, \[\frac{3x+5x+7x}{3}=15000\] \[5x=15000\] \[\Rightarrow \] \[x=3000\] Hence, the price of the cheapest item \[=3\times 3000\] \[=Rs.\,\,9000\]You need to login to perform this action.
