Question
A is 75% more than B. C is 60 less than A. Average of
A, B and C is 340. The ratio of B and C is 2:x. Find the value of x.Solution
Let A be 7a and B be 4a. And C = 7a – 60 According to question, => 7a + 4a + 7a – 60 = 340 x 3 => 18a = 1080 => a = 60 So, B = 4a = 240 And C = 7a – 60 = 360 Now, B /C = 2/x => 240/360 = 2/x => x = 3
