Number of pages typed by Ravi in 1 hour = | 32 | = | 16 | . |
6 | 3 |
Number of pages typed by Kumar in 1 hour = | 40 | = 8. |
5 |
Number of pages typed by both in 1 hour = | ❨ | 16 | + 8 | ❩ | = | 40 | . |
3 | 3 |
∴ Time taken by both to type 110 pages = | ❨ | 110 x | 3 | ❩ | hours |
40 |
= 8 | 1 | hours (or) 8 hours 15 minutes. |

4th observation i.e., 8 is the median.
47/10000 = .0047
.02 =(2/100) x 100% =2%
Let N / 11 = 233
Then, N = 233 x 11 = 2563
? Missing digit is 5.
121012 = 12 x 10084 + 4
? remainder = 4
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
