Options
- A. 1 100(N+1)
- B. 100 N
- C. 10(N+1)
- D. 1 10 N
Answer
A. 1 100(N+1)
Step-by-step solution
V . C=M S D-V S D....(1) given : (N+1) V S D=N MSD VSD = ( N N+1 ) MSD ....(2) From (1) and (2) aligned & V C=( MSD )- N N+1 ( MSD ) \\ & = MSD (1- N N+1 )= MSD N+1 \\ & = 0.01 N+1 = 1 100(N+1) aligned
