##### Topic- Approximation

1.(√80.997 – √25.001) x (√120.98 + √16.02) = ?

• ? = (√81 – √25) x (√121 + √16)
• ? = (9 – 5) x (11 + 4)
• ? = 4 x 15 = 60
• ? = 60

2.55.01 – 345.02÷ 22.99 × 2 = ?

• ? = 55 – 345 ÷ 23 × 2 = 55 – 30
• ? = 15

3.(184.002 – 29 ÷ 5)x 29.997 = X

• (184 – (29/5)) x 30 = X
• X = 5340

4.√(3099.985÷62.001+14.001) = X

• √3100/62 + 14 = X
• √50+ 14 = X
• √64 =X
• X = 8

5.(111.91 x51) ÷14.02 = 11.002 + X

• (112 x 51)/14– 11 = X
• X = 397

6.(84.01 of 24. 97% ÷ 6.995) = ?

• ? = 84 x 1/4 ÷ 7
• ?= 21/7 = 3
• ? = 3
