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

The fund invested by Mr. Boris in B is $ 452.8

Step-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 = 2x

The total profit earn together = 1440

So, The profit earn from fund A = 2x + 8% of 2x = 2.16 x

And The profit earn from fund B = x + 2% of x = 1.02 x

∴  1.02x + 2.16x= 1440

Or, 3.18x = 1440

∴  x = = 452.8

So, The fund invested ib B = x =$ 452.8

Hence The fund invested by Mr. Boris in B is $ 452.8       Answer

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21
