-
A.
7861
-
B.
3369
-
C.
5615
-
D.
10107
Correct Answer:
D. 10107
Explanation:
To find the cost of the least expensive item, multiply the average price of Rs 16845 by 3 to get a total value of Rs 50535. Since the prices follow a 3:5:7 ratio, the total number of parts is 15. The cheapest item accounts for 3 of these parts, so its price is calculated as (3/15) of Rs 50535, which equals Rs 10107.
