9. Total Direct Cost= 1,73,65,000 -
Overheads=25000/day
Total indirect cost= 25000*295= 7375000 -
Total Cost= DC+IDC = 2,47,40,000 -
Step 1: Crash B by 2 days
TC=(17365K+5K)+(293*25K)= 2,46,95,000 -
Step 2: Crash A by 1 day
TC=(17370K+5K)+(292*25K)= 2,46,75,000-
Step 3: Crash J by 2 days
TC=(17375K+10K)+(290*25K)= 2,46,35,000-

10. Step 4: Crash G by 2 days
TC=(17385K+15K)+(288*25K)= 2,46,00,000 -
Step 5: Crash H by 1 day
TC=(17400K+25K)+(287*25K)= 2,46,00,000-
Step 6: Crash C by 1 day
TC=(17425K+50K)+(286*25K)=2,46,25,000 -
Optimum Cost= 2,46,00,000 -
Optimum Duration= 287 days
