If 4P = 5Q and 3Q = 4R, then what is the value of P : Q : R?

Correct option is D

Given:
4P = 5Q
3Q = 4R
Formula Used:
To find P : Q : R, we express each variable in terms of a common value.
Solution:
 From 4P = 5Q, we get P = $$\frac{5Q}4$$​​
From 3Q = 4R, we get R =$$\frac{3Q}4$$​​
P : Q : R =$$\frac{5Q}4:Q:\frac{3Q}4$$​  = 5 : 4 : 3
