Consider a group of working men. If 1/10th of the workers are absent then work of each person would be increased by.

To complete a work, A takes 50% more time than B. If together they take 18 days to complete the work, how much time shall B take to do it?

• [A] 30 days
• [B] 35 days
• [C] 40 days
• [D] 45 days

If 20 men take 15 days to complete a job, in how many days can 25 men finish that work?

• [A] 9
• [B] 10
• [C] 16
• [D] 12
• [E] 15

A can finish a work in 18 days and B can do the same work in 15 days. B worked for 10 days and left the job. In how many days, A alone can finish the remaining work?

• [A] 5
• [B] 5 ¹/₂
• [C] 6
• [D] 8
• [E] None of these

A and B can complete a work in 15 days and 10 days respectively. They started doing the work together but after 2 days B had to leave and A alone completed the remaining work. The whole work was completed in :

• [A] 8 days
• [B] 10 days
• [C] 12 days
• [D] 15 days

A takes twice as much time as B or thrice as much time as C to finish a piece of work. Working together, they can finish the work in 2 days. B can do the work alone in:

• [A] 4 days
• [B] 6 days
• [C] 8 days
• [D] 12 days
