Question 868872: The amount he invested in Fund A was $2000 less than the amount he invested in Fund B. Fund A returned a 7% profit and Fund B returned a 2% profit. How much did he invest in Fund A, if the total profit from the two funds together was $940? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let x be invested in fund B--------------2%
Fund B -----------x-7000------------------7%
interest------------------940 from both
2%x + 7%(x-2000)=940
multiply by 100
2x+7(x-2000)=94000
2x+7x-14000=94000
9x=94000+14000
9x=108000
x=108000/9
x=12000
12000 in Fund B
10000 in Fund A
