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 ? Correct Answer 5/9

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.
