Question
The average of two numbers ‘P’ and ‘Q’ is 480
such that they are in the ratio 5:7 respectively. Another number ‘R’ is 60 more than ‘Q’ and fourth number ‘S’ is 50% of the ‘P’. Find the average of ‘R’ and ‘S’.Solution
Sum of ‘P’ and ‘Q’ = 480 × 2 = 960
Therefore,
‘P’ = 960 × (5/12) = 400
‘Q’ = 960 – 400 = 560
‘R’ = 560 + 60 = 620
‘S’ = 0.5 × 400 = 200
Required average = {(620 + 200)/2} = 410
