Answer:

  • $8571.43

---------------------------------------

Let the initial amount be x.

A woman spent 1/4 of her salary, remainder is

  • x - 1/4x = 3/4x

1/3 of it spent on food and 1/5 on transport

  • (3/4x)(1/3 + 1/5) = 3/4x × 8/15 = 2/5x

Remaining amount is $3000

  • 3/4x - 2/5x = 3000
  • 15/20x - 8/20x = 3000
  • 7/20x = 3000
  • x = 3000×20/7
  • x = 8571.43
