$\text{Cost Slope} = \frac{\text{Crash Cost-Normal Cost}}{\text{Normal Time-Crash Time}}$

Stage 1 :- All Normal

enter image description here

Critical path = 10-20-30-50-70-80-90 i.e. (P-Q-T-V-X)

Project duration = 29 days

Stage 2 :- All Crash

enter image description here

All Crash

Project duration = 20 days

Stage 3 :- Stage 1 + Crash Q by 1 day

enter image description here

All Crash

Project duration = 28 days

Stage 4 :- Stage 3 + Crash T by 1 day + Crash U by 1 day

enter image description here

All critical

Project duration = 27 days

Stage	Description	Duration	Direct Cost	Addition Cost	Total cost
1	All Normal	29	68000	-	126000
2	All Crash	20	98000	-	138000
3	Stage 1 + Crash Q by 1 day	28	68000		125500
4	Stage 3 + Crash T by 1 day + Crash U by 1 day	27	68000		126666.66

Optimum cost = Rs. 125500/-

Optimum duration = 28 days
