Kirt has a $6000 monthly salary when he started his job. After a year of working, his salary increased by 30%. How much are his total earnings after 3 years?
Let's think step by step below.
259200
His annual salary for the first year of working is 6000 x 12 = $72000.

Kirt's monthly increase is $6000 x 30 / 100 = $1800.

So, he received $6000 + $1800 = $7800 monthly on the second and third year of working.

Kirt's annual salary in the second and third year was $7800 x 12 = $93600.

.

Thus, his total earning after 3 years is $72000 + $93600 + $93600 = $259200.

.

So, the final answer is 259200
