Question
If Adam's expenditure is 37.5% more than Andrew's, by what percent is Andrew's expenditure less than Adam's? Ops: A. 25% B. 44.44% C. 27.27% D. 20%
Solution
Let's solve this step by step:
- Let's assume Andrew's expenditure is 100 units.
- According to the problem, Adam's expenditure is 37.5% more than Andrew's. So, Adam's expenditure is 100 + 37.5 = 137.5 units.
- Now, we need to find out by what percent is Andrew's expenditure less than Adam's. This means we need to find out how much less Andrew's expenditure is compared to Adam's, in terms of percentage.
- The difference in their expenditure is 137.5 - 100 = 37.5 units.
- To find this difference as a percentage of Adam's expenditure, we divide the difference by Adam's expenditure and multiply by 100. So, the percentage is (37.5 / 137.5) * 100 = 27.27%.
So, Andrew's expenditure is 27.27% less than Adam's. The answer is C. 27.27%.
