If `l ,m ,n` are the three positive roots of the equation `x^3-a x^2+b x-48=0,` then the minimum value of `(1//l)+(2//m)+(3//n)` equals `1` `2` `3//2` `5//2`

If l ,m ,n are the three positive roots of the equation x^3-a x^2+b x-48=0, then the minimum value of (1//l)+(2//m)+(3//n) equals a 1 b 2 c 3/2 d 5/2

If l ,m ,n are the three positive roots of the equation x^3-a x^2+b x-48=0, then the minimum value of (1//l)+(2//m)+(3//n) equals a 1 b 2 c 3/2 d 5/2

If l,m,n are the three positive roots of the equation x^(3)-ax^(2)+bx-48=0, then the minimum value of (1/l)+(2/m)+(3/n) equals 123/25/2

If l ,m ,n are the three positive roots of the equation x^3-a x^2+b x-48=0, then the minimum value of (1//l)+(2//m)+(3//n) equals (a) 1 (b) 2 (c) 3//2 (d) 5//2

If l,m,n, be the three positive roots of the equation x^(3)-ax^(2)+bx-48=0 , then the minimum value of (1)/(l)+(2)/(m)+(3)/(n) equals (alpha)/(beta) where alpha,beta in N , gcd(alpha,beta)=1 then alpha^(2)+beta^(2)=
