147
152
135
153
None
Option A
Solution:
(4444/ 40) + (645/ 25) + (400 / 40) = x
111.1+ 25.8+ 10=x
x=146.9=147.
2. [(15.9 / 80.01) / (1025.01 -514.75) / 169.65] = ? /29.68
6

2
None
Option D
Solution:
[(16/80)/(1025-515)/170 ]= x/30
16/80 * 170/510 =x/30
1/15=x/30
x=2.
3. (16.01*31.75)/ (8.99*27.01*80.95) =?
(2/3)12
(2/3)9
(2/3)6
(2/3)10
None
Option B
Solution:
(16*32) / (9*27*81) =x
(24 * 2 5) / (32 * 33 *34) =x
(29) /(39)=x
x= (2/3)9.
4. 89.99 +280.01 /3.9 -144.65 = âˆš?
441
289
225
169
None
Option C
Solution:
90+280/4 -145=âˆšx
90+70-145=âˆšx
âˆšx=15
x=225.
5. 80.10% of 179.99 + 44.65% of 30.01 =?
142
139
158
136
None
Option C
Solution:
80% of 180 + 45% of 30=x
144+13.5=x
x=157.5=158.
6. 44.55 + 62.85 – 32.01 + 59.88 – 21.5 = ?
98
114
106
117
None
Option B
Solution:
45+63-32+60-22=x
168-54=x
x=114.
7. (2914.01/31.1) /(1.99/3.01) * 510.01/169.99=?
423
441
386
364
None
Option A
Solution:
(2914/31)* (3/2)*(510/170)=x
47*3*3=x
x=423.
8. âˆš1087.86 + 4.022 =? + âˆš1024.03
28
36
44
17
None
Option D
Solution:
âˆš1088 + 4 2 =x + âˆš1024
33+16-32=x
x=17.
9. 35.22% of 739.82 + ? = (125% of 13.02)2
-3
+3
-6
+6
None
Option A
Solution:
35 % of 740 +x= (125% of 13)2
259 +x=16< sup>2
x=256-259
=-3.

216
512
729
64
Option C
Solution:
90 + 70-151=Â³âˆšx
160-151=Â³âˆšx
Â³âˆšx=9
