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?

Respuesta :

Answer:

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%  = [tex]\frac{0.1x+150}{5000+x}[/tex]

solve it we get

x = 2000

so amount invest in B is 2000
