Of the three numbers second is twice the first and is also their the third .If the average of the three numbers is 44 , find the largest number .
Sol . Let the third number be `x` , Then second number = `3x`. , First number = `(3x)/(2)`
`:.` `x + 3x + (3x)/(2) = (44 xx 3)`
or ` (11x)/(2 ) = 44 xx 3`
or `x = 24`
So , largest number = 2nd number = `3x` = 3 x 24 = 72
