Problema Solution
Pabloinvested his savings in two investment funds. The $6000 that he invested in fund A returned a 7% profit. The amount that he invested in fund B returned a 2% profit. How much did he invest in fund B, if both funds together returned a 5% profit?
Answer provided by our tutors
Let he invested x in fund B. Then,
7*6000 + 2*x = 5*(6000+x)
Or, 42000+2x = 30000+5x
Or x = $4000
