Solution:
1). b)
4, 12, 42, 196, 1005, 6066, 42511
4ร ร 2+(2)2= 12
12ร ร 3+(3)2= 45
45ร ร 4+(4)2= 196
196ร ร 5+(5)2= 1005
1005ร ร 6+(6)2= 6066
6066ร ร 7+(7)2= 42511
Hence, 42 is the wrong number
ย
2). d)
7, 13, 25, 49, 97, 194, 385
7ร ย รย 2 -1= 13
13ร รย 2 -1= 25
25ร  ร 2 -1= 49
49ร รย 2 -1= 97
97ร  ร 2 -1= 193
193ร ร 2 -1= 385
Hence, 194 is the wrong number
ย
3). c)
10, 15, 24, 35, 54, 75, 100
Hence, 35 is the wrong number
ย
4). d)
ย 2, 8, 32, 148, 765, 4626, 32431
2 ร 2+22= 8
3 ร 8+32= 33
4 ร 33+42= 148
5 ร 148+52= 765
6ย ร765+62= 4626
7 ร 4626+72=32431
Hence, 32 is the wrong number.
ย
5). d)
73, 57, 49, 44, 43,42
73-57= 16
57-49=8
49-45= 4
45-43= 2
43-42=1
Differences between the consecutive numbers are in Geometric Progression (G.P)
Hence, 44 is the wrong number.
ย
6). c)
Required percentage= 20 / (100- 80) ร100% = 25%
ย
7). a)
Required percentage= [40 / (100-40)] ร 100% =(40/60) ร 100% = 66 2/3%.
ย
8). d)
Let Nisha salary be 100,
ร  Remaining after expenditure = 25
Nishaโs savings = 60% of 25 =(60/100) ร 25=15
She gave 2100 to her sister, so 25-15= 10
10% = 2100
โด 100% =21000 (Nishaโs salary)
ย Ashaโs salary = 75 % 21000ย  (since, 25% less than Nishaโs salary )
= 15750
โด Ashaโs expenditure= 60% of 15750 = 9,450
ย
9). a)
Let sides of the square be a& b,
ร  โaโ is increased by 30%, the other side โbโ is decreased by = 30+ b+ (30b/100) = 0
= 130b / 100 = 30
B = 23 1/13%
ย
10). e)

Original price of the sugar = (10 ร 300) / [(100 – 10) ร 1] = (10ร300) / (90ร1) = 33.34
