$0.27 * ?^4 = 170.1$
$ ?^4 = 630$
? = 5 approx.
Hence, option E is the correct choice.

2) Answer (B)

$ 273.98 * \frac{3}{7} + \sqrt{840} $ = ? can be approximately written as
$ 273*\frac{3}{7} + \sqrt{841} $ = ?
117 + 29 = 146 approx.
Hence, option B is the correct choice.

3) Answer (C)

18.94% of 264 + ? + 33.1% of 327 = 451 can be approximately written as
0.19 of 264 + ? + 0.33 * 327 = 451
50.16 + ? + 108 = 451
? = 292.84
Hence, option C is the correct choice.

4) Answer (D)

$\frac{\sqrt{2} * (97.97 + ?^2)}{4.24} = 49$ can be approximately written as,

$\frac{49 * 4.24}{\sqrt{2}} =98 + ?^2$

$49 * 3 = 2*49 + ?^2$
$?^2 = 49$
? = 7
Hence, option D is the correct option.

5) Answer (B)

$27.99^2 / 3 + ? = 167.05 + 17*10.4$ can be approximately written as
$28^2 / 3 + ? = 17*10.4 + 167$
784/3 + ? = 176.8 + 167
? = 343.8 – 261.33 = 82.5 approx.
Hence, option B is the correct choice.

? = 14 approx.
Hence, option E is the correct choice.

7) Answer (B)

66.69% of (22.5% of (16.48% of 250.49) = ?
$\frac{2}{3}$ * $\frac{0.9}{4}$ * $\frac{0.33}{2} *250 = ?
? = 6.1875 = 6.2 approx.
Hence, option B is the correct choice.

8) Answer (C)

51.49% of 636 – 82.08% of 211 = ?
0.515*636 – 0.82*211 = ?
? = 327.5 – 173 = 154.5
Hence, option c is the correct choice.

9) Answer (D)

$\frac{\sqrt{421+364} + ?^3}{14.89}$ = 90.6
$\frac{\sqrt{785} + ?^3}{15}$ = 90.6
$\frac{28 + ?^3}{15}$ = 90.6
28 + $?^3$ = 1359
$?^3$ = 1331
? = 11
Hence, option D is the correct option.

10) Answer (B)

$18.98^2 + ? = 31.994 * 17.017 + 574.98/5$ can be approximately written as
