# If P : Q = 2 : 5 , Q : R = 4 : 3, Then Find P : R - ICSE Class 10 - Mathematics

#### Question

If p : q = 2 : 5 , q : r = 4 : 3, then find p : r

#### Solution

p : q = 2 : 5 => "p"/"q" = 2/5

q : r = 4 : 3 => "q"/"r" = 4/3

=> "p"/"q" xx "q"/"r" = 2/5 xx 4/3

=> "p"/"q" = 8/15

p : r = 8 : 15

Is there an error in this question or solution?
