Hong invested his savings in two investment funds. the 5000 that he invested in fund a returned a 3% profit. the amount that he invested in fund b returned a 10% profit. how much did he invest in fund b, if both funds together returned a 5% profit?

amount invest in B is 2000

Explanation:

given data

invested in Fund A = 5000

return profit A = 3%

return profit B = 10%

both together returned profit =  5%

solution

we consider here amount invest in B = x

so profit from fund B is

profit from fund B =  10% ×  x = 0.1 x

and

profit from fund A = 5000 × 3% = 150

so total profit = 0.1x + 150

and total profit = 5%

so we can say

5%  =

solve it we get

x = 2000

so amount invest in B is 2000
