Answers & Solutions:

1) Answer (A)

The expression can be written as:
99*4*88*3*77*2/(11*11*11) = 9*4*8*3*7*2 = 12096

2) Answer (B)

Given expression can be written as 78 * 25 * 9 * 13 + 5
= 228150 + 5 = 228155

3) Answer (B)

6.42 + 8.98 + 10.33 = 25.73
5.34 + 2.79 = 8.13
25.73 – 8.13 = 17.60

4) Answer (D)

56789 + 76543 + 12345 + 98706 – 89012 – 65432 – 23568 = 66371

5) Answer (E)

8948/4 = 2237
5625/25 = 225
48996/9 = 5444
So, the answer is 2237+225+5444 = 7906

6) Answer (C)

$\sqrt{15376}=124\\$
$\sqrt{1/576}=1/24$
$So, the expression boils down to $124/24=31/6=5\ \frac{1}{6}$

7) Answer (E)

2268000/90 = 25200
25200/36 = 700
700/14 = 50
So, ? = 50

8) Answer (E)

The given expression can be simplified as:
121 + 169 + 225 + 289 – 144 – 196
= 804 – 340 = 464

9) Answer (A)

The smallest number that is a perfect square as well as a perfect cube is $2^{6}=64$
$64^{2}=4096$
So, 4100 – 4096 = 4 has to be subtracted from 4100 to get a number that is a perfect square as well as a perfect cube.

10) Answer (C)

Let the number be N.
75/100 * 34/100 * N = 125 => N = 125*100*100/(75*34)
=> 170% of N = (170/100) * 125 * 100 * 100/ (75*34) = 5*125*100/75 = 5*5*100/3 = 2500/3 = 833.33
