The salary of a man was increased in the ratio 40:47. calculate the percentage increase in the salary
Answer Details
To calculate the percentage increase in the salary of a man, we need to find the difference between the new and old salary and then express it as a percentage of the old salary.
Let's assume the old salary was 40x and the new salary is 47x (where x is a constant).
Then, the increase in salary = 47x - 40x = 7x.
Now, the percentage increase in salary = (increase in salary / old salary) x 100%
= (7x / 40x) x 100%
= 17.5%
Therefore, the percentage increase in the salary of the man is 17.5%. Answer is correct.
