Answer 1

Answer:

46,666.667

Step-by-step explanation:

First, you have to find a common multiple of 20, 3, and 6, I use 60.

Next, you have to convert each fraction to have a denominator of 60:

1/20*3/3 = 3/60

1/3*20/20 = 20/60

1/6*10/10 = 10/60

Then, you want to find what fraction Malti didn't spend:

(3+20+10)/60 = 33/60

(60-33)/60 = 27/60

Now, we know that 21000 = 27/60x (x being her salary) so we can simplify in terms of x:

(27/60)x = 21000

*60

27x = 1260000

/27

x = 46666.666....

Therefore, Malti's salary is 46,666.667
