the value of multipler is :(choose the correct alternative )
(a) `(1)/(MPC)` (b) `(1)/(MPS)` (c )` (1)/(1-MPS)` (d) `(1)/(MPC-1)`

If MPC=MPS, the value of multiplier is:

if MPC =1, the value of multiplier is ___________:

a, b, c, d and e are integers .If a, b, c, d and e are geometric progression and lcm(m, n) is the least common multiple of m and n, then the maximum value of (1)/(1cm (a,b)) + (1)/(1cm (b,c)) + (1)/(1cm(c,d)) + (1)/(1cm (d,e)) is
