Approximation Test-4 (Approximation of decimal figures)

Answer: Option A

Explanation

Given,

14.998% of 619.999 =?

It can also be approximated as

15% of 600=?

= $\frac{15}{100}$×600

= 90 ≈ 95

Hence, Option A is correct.

Answer: Option E

Explanation

Given,

√?=37.0005

It can be approximated as

√?=37.005

 = (37)²

= 1369 ≈ 1370

Hence, Option E is correct.

Answer: Option B

Explanation

Given,

1088.88 + 1800.08 + 1880.80 = ?

It can also be added

1100 + 1800 + 1900 = ?

= 2900+1900

= 4800 ≈ 4770

Hence, Option B is correct.

Answer: Option A

Explanation

Given,

389÷(26×6.9)=?

It can also be approximated as

400÷(3×7)=?

= 400÷21

= 19 ≈ 22

Hence, option A is correct.

Answer: Option D

Explanation

Given,

74% of 366+ 12.6% of 317=?

It can be approximated as

70% of 370+ 13% of 320=?

= 259+13×32

= 259+4.16

= 300.6 ≈ 310

Hence, Option D is correct.
