Of the four numbers , the first is twice the second, the second is one -third of the third and the third is 5 times the
fourth. The average of the numbers is 24.75. The largest of these numbers is :
Let the fourth number be `x`
Then , third number = 5`x`, second number = `(5x)/(3)` and first number = `(10x)/(3)`
`x + 5x +(5x)/(3) + (10x)/(3)` = 24.75 x 4 or `11x ` = 99 or `x` = 9
so the numbers are 9, 45, 15 and 30
`:.` Largest number = 45.
