If 6 × P's capital = 8 × Q's capital = 10 × R's capital, find the ratio of their capitals?

Question: If 6 × P's capital = 8 × Q's capital = 10 × R's capital, find the ratio of their capitals?

Solution:
Let,
6 × P's capital = 8 × Q's capital = 10 × R's capital = x
Now,
P's capital = x/6
Q's capital = x/8
R's capital = x/10

∴ Ratio of capitals of P, Q, R = x/6 : x/8 : x/10
= 20 : 15 : 12
