Let suppose the three numbers are 4y, 5y and 6y.
The average of three numbers
(4y + 5y + 6y)/3 = 25 ________ (i)
Through equation (i) we can easily find out the value of y (y = 5) and largest number (6 x 5 = 30).
Largest Number = ?
Three Numbers = 4y, 5y and 6y
According to the given condition
(4y + 5y + 6y)/3 = 25
15y = 75
y = 75/15
y = 5
Largest Number = 6 x 5 = 30 answer
Three numbers are in the ratio 4:5:6 and their average is 25. The largest number is 30.
