First, the salary increased by 10%, and then by another 30%. By what percentage has the salary increased compared to the initial one?

Let’s denote the initial amount of salary for x.

Let’s determine the size of the salary after the first increase:

x + 0.1 * x = 1.1 * x.

Let’s determine the size of the salary after the second increase:

1.1 * x + 0.3 * 1.1 * x = 1.1 * x + 0.33 * x = 1.43 * x.

Let’s find the ratio of the size of the final salary to the initial one:

1.43 * x: x = 1.43, which corresponds to an overall salary increase of 43 percent.

Answer: 43%.
