1. A salesman's income consists of his salary and commission . His monthly salary is TK. 8,000. During one month, the commission he earned was 5/4 of his salary . What fraction of his income for that month came from commission ?
- A. 5/9
- B. 5/9
- C. 5/9
- D. 5/9
Answer: Option A
Explanation:
The salesman's commission for the month is 5/4 * 8000 = 10000.
Therefore, his total income for the month is 8000 + 10000 = 18000.
The fraction of his income that came from commission is:
10000 / 18000 = 5/9.
So, 5/9 of his income for the month came from commission.
