A certain number of persons can complete a piece of work in 55 days. If there were 6 persons more, the work could be finished in 11 days less. How many persons were originally there ?
-
- 17
- 24
- 30
- 22
Correct Option: B
Originally, let there be x men
Now, more men, less days
(x + 6) : x : : 55 : 44
| So, | = | = | ||||
| x | 44 | 4 |
or 5x = 4x + 24
or x = 24
Aliter : Using Rule 23,
Here, D = 55. a = 6, d = 11
No of people initially
| = | d |
| = | = 24 | 11 |
