Answer:
The correct answer is - 72,349.2
Step-by-step explanation:
Given:
selling price = 7234.92
Initial profit = 16%
we know:
selling price = cost price + profit
Solution:
78300 = cp + 16*cp/100
profit = 78300*16/100 = 12528
cost price = 78300 - 12528 = 65772
then the profit on 10%
= 65772*10/100
= 6577.2
the new selling price = 65772+6577.2
= 72,349.2
