Simplification and Approximation Questions for SBI Clerk, CET, IBPS Clerk, IBPS RRB, LIC Assistant with PDF

Direction: What approximate value should come in the place of question mark (?) in the following questions?
Important for :
1
(51.012 + 36.012) ÷ 8.99 + √? = 460
» Explain it
A
(51.012 + 36.012) ÷ 8.99 + √? = 460

⇒ {(2601 + 1296) / 9} + √? ≈ 460

⇒ 433 + √? = 460

⇒ √? = 460 – 433

⇒ √? = 27

? = 27 × 27 = 729.

Hence, option A is correct.

2
(1600.01 ÷ √? × 54.02) ÷ 20.09 = 144.02
» Explain it
D
⇒ {(1600 / √?) × 54} × (1 / 20) = 144

⇒  {(80 × 54) / √?} = 144

⇒ √? = {(80 × 54) / 144}

⇒ √? = 30

∴ ? = 900

Hence, option D is correct.

3
40.01% 900.09 + (7.07 × 99.99) ÷ 14.14 + ? = 70.07% of 7000
» Explain it
A
40% 900 + {(7 × 100) / 14.14} + ? ≈ 70% OF 7000

⇒ (40 / 100) × 900 + 50 + ? ≈ (70 / 100) × 700

⇒ 360 + 50 + ? ≈ 4900

⇒ ? = 4900 – 410

∴ ? = 4490

Hence, option A is correct.

4
(7.01)3 × (12.01)2 ÷ √2402 = (?)3
» Explain it
B
⇒ (?)3 = [{(7)3 × (12)2} / √2401]

⇒ (?)3 ≈ {(343 × 144) /49}

⇒ (?)3 ≈ 1008

⇒ (?)3 ≈ (10)3

∴ ? = 10

Hence, option B is correct.

5
5555 ÷ 42 × (19)2 + 64.5 = ?
» Explain it
D
5555 × (1 / 42) × (19)2 + 64.5

? = 47746.546 + 64.5

? = 47811.046 ≈ 47811.

Hence, option D is correct.
