If p : q is 5 : 6 and q : r is 2 : 5, then what is p : q : r?
Show answer & explanation
Correct answer: C
Explanation
The correct option is option 3 i.e. 5 : 6 : 15.
Given :
p : q = 5 : 6 ....(i)
q : r = 2 : 5 .....(ii)
Explanation :
Multiplying equation (ii) by 3
q : r = 6 : 15 ....(iii)
Now we have,
p : q : r = 5 : 6 : 15
Hence the required ratio of p : q : r = 5 : 6 : 15.
