The cost of a flower vase increased by 12%. If the current cost is ₹896, what was its original cost
Solution:
Given, the cost of a flower vase increased by 12%.
After the increase, the cost is ₹896.
We have to find the original cost.
Let the original cost = x
According to the question,
896 = x + 12% of x
896 = x + (12/100) × x
896 = x (1 + 12/100)
896 = x[(100+12)/100]
896 = x(112/100)
x = 896 × (100/112)
x = 8 × 100
x = 800
Therefore, the original cost is ?800.
