Explanation
The correct answer is Option 2 i.e. 4.4
| Understanding/Application |
|
√18 = 4.24 Now, 2 × 4.24 = 8.48 and, 11 + 8.48 = 19.48 Therefore, √19 = 4.41 TRICK: 52 = 25 and 42 = 16, we have to find √19+ so it must lay between 4 and 5 and 19 is much near to 16 so the answer is also must lay near to 4, i.e 4.4, we eliminate option 1 i.e 4.8 |
