dem82 [27]

Answer: $100,000


Step-by-step explanation:

Let P be the amount he invested in 5% profit .

then 250,000-P be the amount he invested in 10% profit .

The total profit he earns at 5% =5% of P

⇒The total profit he earns at 5 %=0.05P

Now, The total profit he earns at 10% =10% of (250,000-P)

⇒The total profit he earns at 10%=0.1(250,000-P)=25,000-0.1P

According to the question,

3(0.05P)=25,000-0.1P\\\Rightarrow\ 0.15P=25,000-0.1P\\\Rightarrow\ 0.25P=25,000\\\Rightarrow\ P=\frac{25000}{0.25}\\\Rightarrow\ P=100,000

Thus, the money he invest in the company that made 5%= $100,000
