Respuesta :

Answer:E

Step-by-step explanation:

It is given that there is approximately 2% rise in portfolio.

Also one stock is decrease by 35% and another is increase by 15 %

It is clear that if there is 2 % rise in portfolio then 15 % of suppose stock P must be suppose 35 % of stock Q

thus P must be twice or even greater than twice of Q  so P and Q must be

20 and 70 because

35 % of 20= 7

15 % of 70= 10.5

so remaining stocks should be $35 , $40 , $45
