Miss Huangs monthly salary is $1650. She spends 2 5 of it, give 1 3 of the remainder to her mother and saves the rest. How long will she take to save $5940?

1 answer

From her monthly salary of $1650, Miss Huang spends 2/5 * 1650 = $<<2/5*1650=660>>660
After spending, she remains with 1650 - 660 = $<<1650-660=990>>990
Out of the remainder, she gives her mother 1/3 * 990 = $<<1/3*990=330>>330
The amount of money Miss Huang saves is 990 - 330 = $<<990-330=660>>660
If she saves $660 a month, it will take her 5940/660 = <<5940/660=9>>9 months to save $5940. Answer: \boxed{9}.
