Answer 2

Answer:

please mark me branlist

Then using

Ratio of investments = ratio of proportions

4t1:6t2:9t3=2:3:54t1:6t2:9t3=2:3:5

Taking two first terms of the ratio,

4t16t2=23=>t1t2=11=994t16t2=23=>t1t2=11=99

= > t1:t2=9:9t1:t2=9:9

Taking last two terms of the ratio,

6t29t3=35=t2t3=9106t29t3=35=t2t3=910

= > t2:t3=9:10t2:t3=9:10

So t1:t2:t3=9:9:10t1
