(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13- Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
For each ordered triple $$(a,b,c)$$ observe the relation between the first, second and third numbers.
Compute the difference between the second and first numbers for the given triples:
$$b-a \;=\;14-5=9 \quad\text{when }(a,b,c)=(5,14,3)$$
$$b-a \;=\;24-3=21\quad\text{when }(a,b,c)=(3,24,7)$$
Now compare these differences with the third numbers:
$$9 = 3 \times 3 \qquad\text{and}\qquad 21 = 7 \times 3$$
The common pattern is therefore
$$b-a = 3c \quad\Longrightarrow\quad c = \frac{b-a}{3}$$
Apply this rule to the third triple $$(9,30,?)$$:
$$c = \frac{b-a}{3} = \frac{30-9}{3} = \frac{21}{3} = 7$$
Hence the missing number is $$7$$.
Option A which is: 7

In each of the following questions, find out the wrong number in the series.
17, 23, 31, 41, 53, 69
here we need to find the odd one out in 17, 23, 31, 41, 53, 69
as we can see that
23 - 17 = 6
31 - 23 = 8
41 -31 = 10
53 - 41 = 12
69 - 53 = 16
here we can see that difference between consecutive terms is increasing by 2 every single time but in last case the difference increased by 4 and hence 69 is the odd one out .
In each of the following questions, select the missing number from the given responses.
let the missing term be y
here as we can see in column 1 and column 3 , terms of column 3 are sqaures of terms in column 1

let the missing term be y
here in column 1st and 2nd we can see that
product of 1st two terms = product of last two terms
25 x 12 = 5 x 60 (in 1st column)
18 x 17 = 2 x 153 (in 2nd column)
so this pattern will follow for 3rd column also
and hence , 36 x 16 = y x 96
y = 6

899-891 = 8 = (2)^3
891-864 = 27 = (3)^3
864-800 = 64 = (4)^3
as we can see the pattern between differences of consecutive numbers is of type (n)^3
so x-800 = (5)^3,this implies that x= 675

here we can see that every term is a power of 5
1 = 5 ^ 0
5 = 5 ^ 1
25 = 5 ^ 2
125 = 5 ^ 3
so the next term will also be power of 5 and the terms are 5 ^ 4, 5 ^ 5 , 5^6 i,e 625, 3125, 15625

38 - 11 = 27 = 3^3
102 - 38 = 64 = 4^3
227 - 102 = 125 = 5^3
hence y - 227 = 6^3 = 216
y = 216 + 227 = 443

86 -9 =77
77 -11 =66
66-13 =53
So option C is correct

$$ 16^{2} $$ = 256
respectively
40% of 1620 + 30% of 960 = ? % of 5200
40% of 1620 = $$\frac{40 \times 1620}{100}$$ = $$ 648 $$
30% of 960 = $$\frac{30 \times 960}{100}$$ = $$ 288 $$
648 + 288 = 936
Let the unknown percentage be $$x$$.
$$ 936 = x \% of 5200$$
$$x = \frac{936 \times 100}{5200} = 18 $$

here the given pattern is 102, 101, 98, 93, 86, 74, 66, 53
as we ca see that
102 - 101 = 1
101 - 98 = 3
98 - 93 = 5
93 - 86 = 7
as we can see that the difference between consecutive terms is increasing by 2 in every case but when we check
86 - 74 = 12 we see that the pattern is not getting fullfilled in case of 74 so in order to make the same pattern the term should be 77 inspite of 74 .
lets check with 77
86 - 77 = 9
hence it is confirmed that the wrong number is 74
