Official Solution:

If in a $180 mln portfolio of stock, twice as much is invested in stock A as is invested in all the other stocks, how much is invested in all the other stocks?

A. $60 mln
B. $80 mln
C. $100 mln
D. $120 mln
E. $150 mln

Let \(x\) denote the amount invested in all the other stocks. Then the amount invested in stock A is \(2x\). As we have the $180 mln portfolio, \(x + 2x = 3x = 180\) mln from where \(x = 60\) mln.

Answer: A

we can also solve by plugging number.
lets start with B
since other stocks is 80 million, investment in A will be 80*2 = 160...
160 (A) + 80 (other) > 180....hence we need a lower 'other investment'.

Hence option A is correct

Hi Bunuel,

When it is mentioned that twice A as much as B then it has to be A = 2B. If we consider x as the investment then it has be x+2x = 180. Other stocks value should be 120. Can you let me the relation.

Hi msk0657,

Twice as much as A = other stocks

Let B = other stocks
2A = B

Total = 3 portion

180 / 3 = 60 = B = other stocks
