She spent (1/4)+(1/3) or 7/12 of her income at the first two and 2/5 of the remainder, or 2/5*5/12=1/6 at the workshop.
Therefore, she spent 7/12 +2/12 altogether or 9/12 or 3/4
1/4 left is 225000GHC
Her monthly income is 4 times that or 900000GHC ANSWER
She spent 1/4 or 225000 at the mall
1/3 or 300000 at the open market ANSWER
and had 375000 left. Two-fifths of that is 150000, and she spent that at the workshop, leaving her with 225000GHC
