| Directions: What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value.) |
| \[\sqrt{2498}\times \sqrt{626}\div \sqrt{99}=?\] |
A) 110
B) 90
C) 200
D) 160
E) 125
Correct Answer: E
Solution :
| \[\sqrt{2498}\times \sqrt{626}\div \sqrt{99}=?\] |
| \[\Rightarrow \] \[\sqrt{2500}\times \sqrt{625}\div \sqrt{100}\approx ?\] |
| \[\Rightarrow \] \[50\times 25\div 10\approx ?\] |
| \[\Rightarrow \] \[50\times 2.5\approx ?\] |
| \[\therefore \] \[125\approx ?\] |
