What should come in place of question mark (?) in the following questions ?
(8.2% of 365)-(1.75% of 108)= ?
16.02
28.04
42.34
53.76
None of these
8.2% * 365 = 29.93
1.75% * 108 = 1.89
So, 8.2%*365 - 1.75%*108 = 29.93 - 1.89 =28.04
$$[(135)^{2}\div15\times32)]\div?=45\times24$$

The number in the place of the question mark equals $$\frac{135^2 \div 15 \times 32}{45 \times 24} = \frac{135 \times 135 \div 15 \times 32}{45 \times 24}$$
$$\frac{135\times135\div15\times32}{45 \times 24}=\frac{9 \times 9 \times 32}{3\times24}=36$$

$$ (96)^{2}+(63)^{2}=(?)^{2}-(111)^{2}-8350$$
33856

184
Let the number in the question mark be X.
So, $$X^2 = 96^2 + 63^2 + 111^2 + 8350$$
So, $$X^2 = 9216 + 3969 + 12321 + 8350 = 33856 = 184^2$$
So, $$X = 184 $$
4368+2158-596-?=3421+1262
1066
1174
1247
1387
So, X = 4368+2158-596-3421-1262 = 1247
$$2172\div?=1832-956-514$$

Let them number in the question mark be X.
So, $$2172 \div $$ X $$=1832 - 956 - 514 = 362$$
So, $$2172 \div$$ X = $$362$$
Or, X $$=2172 \div 362 = 6$$
666.06+66.60+0.66+6.06+6+60=?
819.56
808.38
826.44
798.62
The number in the question mark equals 666.06 + 66.60 + 0.66 + 6.06 + 6 + 60 = 805.38
15.594-4.312-3.517-1.689=?
6.706
6.760
6.670
6.607
The number in the question mark equals 15.594 - 4.312 - 3.517 - 1.689 = 6.076
As it doesn't equal any of the four options, the correct answer is 'None of These'
$$205\times?\times13=33625+25005$$
22
27

39
Let the number which should be used in place of the question mark equals X.
Hence, $$205 \times$$ X$$\times 13 = 33625 + 25005 = 58630$$
So, $$205 \times$$ X $$= 4510$$
So, X$$= 22$$
$$69\div3\times0.85+14.5-3=?$$
36.45
23.85
42.95
18.65
$$69 \div 3 = 23$$
$$23 \times 0.85 = 19.55$$
So, $$19.55 + 14.5 - 3 = 31.05$$
As this is not given in the list of options provided, the correct answer is 'None of these'
$$(10)^{24}\times (10)^{-21}=?$$

1000
By rule of indices,
ab  x   ac = ab+c       Â
Hence, by this rule, we can solve as,
$$(10)^{24}\times (10)^{-21}= (10)^{24-21} =10^3 = 1000$$
Therefore, correct option is D.
