Question

Three people invest in a business. The first two invest in the ratio 2:3, and the third person
invests twice as much as the other two combined. The total investment is $30 million.
How much did the major investor contribute?

Answer 1

Answer:

$15 million

Explanation:

The three investors' total investments would add up to  100% or 1.

The first two invested in the ration of 2:3

It means ;

Investor 1:  2/5

Investor 2: 3/5

If investor 3 invested twice as investor 1 and 2, then we can deduce that he invested ( 2/5 + 3/5) x 2

the  new denominator is 10, meaning

Investor 1 had 2/10,

investor 2 had 3/10

investor 3 had 5/10

If total investments were $30 million, then the highest investor invested

5/10 x $30million

=0.5 x $30 million

=$15 million
