Let x be the amount of money Shanee has..
Raja will have 1.2x (in comparison to Shanee)
John will have 0.8x
Ratio of John : Shanee : Raja
1.2x : x : 0.8x (divide everything by “x”) and you will get......
J : S : R = 1.2 : 1 : 0.8 = 6 : 5 : 4 (ans)

Umm sorry but can you write down? Because i dont really understand
We’ll let Shanee’s money be the reference point which means we will comparing the money of Raja and John to Shanee’s.
Shanee’s money will be 100% and since Raja has 20% more, Raja’s money will be 120% in comparison to Shanee’s money. Since John has 20% lesser as compared to Shanee, John’s money will be 80% of Shanee’s one.
So the ratio of Raja’s money : Shanee’s money : John’s money is 120 : 100 : 80.
you can further simplify it to 6 : 5 : 4.
Uhm... understand ? XD
