Boris invested his savings in two investment funds. The amount he invested in fund A was twice as much as the amount he invested in fund B. Find A returned 8% profit and fund B returned a 2% profit. How much did he invest in fund B, if the total profit from the two funds together was 1440

Answer:The fund invested by Mr. Boris in B is $ 452.8Step-by-step explanation:Given as :The profit percentage return from fund A = 8 %The  profit percentage return from fund B = 2 %Let the amount invested in fund B = x So ,  The amount invested in fund A = 2xThe total profit earn together = 1440 So, The profit earn from fund A = 2x + 8% of 2x = 2.16 xAnd The profit earn from fund B = x + 2% of x = 1.02 x∴  1.02x + 2.16x= 1440Or, 3.18x = 1440∴  x = [tex]\frac{1440}{3.18}[/tex] = 452.8 So, The fund invested ib B = x =$ 452.8Hence The fund invested by Mr. Boris in B is $ 452.8       Answer
