# Concept of Approximation

This portion covers about 5 questions in Bank PO Quantitative Aptitudeâ€™s section.

This is one of the easiest and high scoring portion. One needs to solve the questions of approximation by taking the nearest approximate values and mark the answers accordingly.

Note:- If it is given 3.009 then the approximate value is 3

If it is given 6.99 then the approximate value is 7

But if it is given 4.45 then we will take it 4.50, not 4 or 5.

Example-1
2959.85 Ã· 16.001 â€“ 34.99 = ?
1. 160
2. 150
3. 140
4. 180
5. 170
Solution
? = 2959.85 Ã· 16.001 â€“ 34.99

â‰ˆ 2960 Ã· 16 â€“ 35

â‰ˆ 2960/16 â€“ 35

â‰ˆ 185 - 35

â‰ˆ 150

Example-2
(1702 Ã· 68) Ã— 136.05 = ?
1. 3500
2. 3550
3. 3450
4. 3400
5. 3525
Solution
? = (1702 Ã· 68) Ã— 136.05

â‰ˆ (1700 Ã· 68) Ã— 136

â‰ˆ 3400

Example-3
16.5 x 2400 = 2/3 of ?
1. 588
2. 594
3. 592
4. 590
5. 582
Solution
We know 16.5 % = 1/6(very closely)

Now the question is 1/6 x 2400 = 2/3 of ?
