5 - 10 + 125 = (5)² - 20 + 25 x 55 2 5 25

= 5 - 20 + 50 25

= 35 x 5 25 5

= 355 10

= 7 x 2.236 2

= 7 x 1.118

= 7.826

Answer : Option C

Explanation :

$MF#%\sqrt{0.0576 \times x} = 0.24. \\\\ \Rightarrow
0.0576 \times x = (0.24)^2 \\\\ \Rightarrow 0.0576 \times x = 0.0576 \\\\ \Rightarrow x = 1$MF#%

6 * 15 * 3 = (√(6 + 2)(15 + 3)) / (3 + 1)
= (√8 * 18) / 4 = √144 / 4
= 12 / 4 = 3.

(.000216)^1/3 = 216 1/3 10⁶

   = 6 x 6 x 6 1/3 10² x 10² x 10²

   = 6 10²

   = 6 100

   = 0.06

Answer : Option C

Explanation :

Let n be the number of rows
Then n × n = 49284

$MF#%\text{ie, n = }\sqrt{49284} = 222$MF#%

Answer : Option D

Explanation :

$MF#%\sqrt{41-\sqrt{21+\sqrt{19 - \sqrt{9}}}} = \sqrt{41-\sqrt{21+\sqrt{19 - 3}}} = \sqrt{41-\sqrt{21+\sqrt{16}}}\\\\\ =\sqrt{41-\sqrt{21+4}} =\sqrt{41-\sqrt{25}}=\sqrt{41-5} =\sqrt{36} = 6$MF#%

2|64009( 253 |4 |---------- 45|240 |225 |---------- 503| 1509 | 1509 |---------- | X |----------

64009 = 253.

Answer : Option C

Explanation :

Let the number of members = n
Then n² = Total amount of money collected = 9801 paise

$MF#%\text{ie, }n=\sqrt{9801} = 99$MF#%
i.e., number of members = 99

√192 - (1 / 2)√48 - √75
= √64 * 3 - (1/2) √16 * 3 - √ 25 * 3
=8√3 - (1/2) * 4√3 - 5√3
=3√3 - 2√3
= √3
= 1.732
