And investor invested a total of 2000 500 into mutual funds one fun earned and 9% profit while the other only 2% profit if the i
topjm [15]

Answer:

The amount invested in first mutual fund  = P = 1800

The amount invested in second fund = 700

Step-by-step explanation:

The total amount invested in two mutual funds  = 2500

The total profit earned in both mutual funds  = 176

The profit percent in first mutual fund  = 9%

The profit percent in second mutual fund  = 2%

Now, let us assume the amount invested in first mutual fund = P

So, the amount invested in second fund  = 2500 - P

Calculating the profits ,we get:

9% of P  = \frac{9}{100}  \times P = 0.09P

2% of ( 2500 - P)  = \frac{2}{100}  \times (2500 -P) = 0.02(2500 -P)

Also, total profit = 176

⇒Profit Amount from (First  + Second) mutual fund  = 176

⇒0.09 P + 0.02(2500 -P)  = 176

or, 0.09 P + 50 - 0.02 P = 176

or, 0.07 P = 126

or, P = 126/0.07 =  1800

or, P = 1800

Hence, the amount invested in first mutual fund  = P = 1800

The amount invested in second fund = 2500 - P = 2500- 1800 = 700

mrs_skeptik [129]

Answer:

the density of the iron is  7.9 g /cm^3

Step-by-step explanation:

The computation of the density of the iron is shown below:

Density = weight ÷ volume

= 474 ÷ (5 × 3 × 4)

= 474 ÷ 60

= 7.9 g /cm^3

Hence, the density of the iron is  7.9 g /cm^3
