16 men can finish a job in 16 days, If after 4 days manpower is increased by 14, then How many days will be needed to finish the job?
–In Hindi–
16 aadmi 1 kaam ko 16 dino me pura karte hai agar 4 din baad 14 aadmi bada dete hain to kitne dino me kaam pura hoga?
16 men can do a job in 16 days, after 4 days remaining work can be finished in 12 days by 16 men. But now as we have 14 more persons to do the job, so it can be finished in 12*16/30 = 6.4 days.
More explanation:-
16 men can finish a job in 12 days.
1 man can do the same job alone in 12*16 days.
30 men can do the same job in 12*16/30 days.
