Hello how do solve this
Aasim received a 10% raise each month for 3 consecutive months. If his salary after the
3 raises is 13310, what was his starting salary?
(A) 9000
(B) 10000
(C) 11000
(D) 12000 (E) None of these
Let Aasim’s starting salary be x.
He receives a 10% raise each month for 3 consecutive months.
After 1st month: Salary = 1.1 * x
After 2nd month: Salary = 1.1 * (1.1 * x) = 1.1^2 * x
After 3rd month: Salary = 1.1 * (1.1^2 * x) = 1.1^3 * x
We are given that after 3 months, his salary is 13,310.
So,
1.1^3 * x = 13310
Now, solve for x:
1.1^3 = 1.331
x = 13310 / 1.331
x = 10000
Thus, Aasim’s starting salary was 10,000.
Answer: (B) 10000
