Solution:

(3) Let the number of matches played between India and Pakistan in the first case be x. Number of wins by Pakistan =

= {60 x}/{100}= {3 x}/{5}

According to the question,

{ {3 x}/{5}}/{x+30}= {30}/{100}

⇒{3 x}/{5(x+30)}= {3}/{10}

⇒{x}/{x+30}= {1}/{2}

⇒ 2 x=x+30

⇒ x=30

∴Total number of matches = 30 + 30 = 60
