In January, Joyce kept 80% of her salary of which she then gave 1/5 to her mother and saved the rest. The rest of her money was spent on food and clothing.In February,she gave her mother $150 more than the amount she had given her in January. The amount given to her mother was then equal to the amount she saved.She spent the same amount on food and clothing in January and February.

Question: What was the percentage increase in the amount Joyce gave to her mother in February?

Answer 1: 80%x1/5=16%; 80%x1/2=40%; 40%-16%=24%; 24%---->$150;

so gave mother in January : 16%---> $100;

gave mother in Feb: 40%----> $250

percentage increase: ($250-$100)/$100x100%=150%

Answer 2: In January: gave her mother 16%; In February, gave her mother 40%

so percentage increase: 40%-16%=24%

Please tell which answer is right? If Answer 1 is right, what kind of question expression may get Answer 2? If Answer 2 is right, what kind of question expression may get Answer 1?
