If x = 3 + 2√2, then the value of | ❨ | √x | - | 1 | ❩ | is: |
√x |
❨ | √x | - | 1 | ❩ | 2 | = x + | 1 | - 2 |
√x | x |
= (3 + 2√2) + | 1 | - 2 |
(3 + 2√2) |
= (3 + 2√2) + | 1 | x | (3 - 2√2) | - 2 |
(3 + 2√2) | (3 - 2√2) |
= (3 + 2√2) + (3 - 2√2) - 2
= 4.
∴ | ❨ | √x | - | 1 | ❩ | = 2. |

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
