A company's profits have doubled for each of the last 5 years . If the total profits for the last 5 years were TK. 62 million , what were the profits in the first year ?
- A. 1
- B. 1
- C. 1
- D. 1
Answer: Option B
Explanation:
Let, first year profit = x, as profit have doubled for each year, so
2nd year profit = 2x
3rd year profit = 2x ×2 = 4x
4th year profit = 4x×2 = 8x
5th year profit = 8x × 2 = 16x
Total profit = x + 2x + 4x + 8x + 16x = 31x
According to the question
31x = 62
x = 2
