a)  640
b)  750
c)  340
d)  360
e)  680

7). (77.987 % of 358) + (68.55% of 729) = ?
a)  780
b)  705
c)  840
d)  825
e)  695

8). โ624.995 + (4.9989)2 = ? รท (1 / 4.9900865)
a)  18
b)  34
c)  44
d)  10
e)  25

9). 989.001 + 1.00982 ร 76.792 = ?

10). 63.9872 ร 9449.8780 รท 243.003 = (?)2
a)  60
b)  75
c)  90
d)  40
e)  50

1). C)The series is 3 x3 + 5 = 14, 14 x 4 โ 6 = 50,
50 x 5 + 7 =257, 257 x 6 โ 8 = 1534, 1534 x 7 + 9 = 10747,

2). B)The series is
543 + (5)3 = 668, 668 + (6)2 = 704, 704 + (7)3 = 1047, 1047 + (8)2 =1111
1111 + (9)3 = 1840

3). D)Add the previous number to get the next number.
ie 71 + 78 = 149, 149 + 78 = 227, 227 + 149 = 376, 376 + 227 = 603, 603 + 376 =979, …

4). E)The series is
88ร0.5 = 44, 44ร1.5 =66, 66ร2.5 = 165, 165ร3.5 = 577.5, 577.5ร4.5 = 2598.75

5). A)The series is
3 x 2 + 3 =9, 9 x 3 + 4 = 31, 31 x 4 + 5 = 129, 129 x 5 +6 = 651, 651 x 6+ 7 = 3913, …

6). C)
[( โ530 x 36.003) รท 47.987] x ? = 5863.10376
? = 5863 / [( โ529 x 36) รท 48] = 5863 / [(23 ร 36) รท 48] = 340

7). A)
? = (77.987% of 358) + (68.55% of 729)
? = [(78/100) ร 358] + [(69/100) ร 725]
= 280 + 500 = 780

8). D)
โ624.995 + (4.9989)2
= ? รท (1 / 4.9900865)
or, โ625 + (5)2= ? รท (1/5)
? = 1/5 (25 + 25) = 10

9). B)
? = 989.001 + 1.00982 ร 76.792
= 990 + 1 x 76.8 = 1066.8 = 1070

10). B)
(?)2= 63.9872 x 9449.8780 รท 243.0034
= 64 x 9450 รท 243 = 64 x 39 = 2496
Now, (?)2 = 2496

? = 50
