number analogy Detailed Explanation And More Example

Answer: (b)

$$\text"The relationship is"$$ x : x².

As, $$(\text"1" / \text"9"\)^2 = (\text"1" / \text"81"\).\text" Similarly", (\text"1" / \text"13"\)^2 = (\text"1" / \text"169"\)$$

Answer: (c)

As, Sum of digits of 583 = 5 + 8 + 3 = 16

and Sum of digits of 488 = 4 + 8 + 8

Similarly, Sum of digits of 293 = 2 + 9 + 3 = 14

and Sum of digits of "378" = 3 + 7 + 8 = 18

Here, difference of both sum of digits are (20 - 16) = (18 - 14) = 4.

Answer: (c)

$$\text"The relationship is"$$ x : x².

As, $$\text"12":\text"12"^2=\text"12" :\text"144".$$

$$\text" Similarly",\text"40":\text"40"^2=\text"40" :\text"1600"$$

Answer: (b)

$$\text"The relationship is"$$ x² : (x + 2)².

As, $$\text"7"^2:(\text"7"+\text"2")^2=\text"49" :\text"81".$$

$$\text" Similarly",\text"10"^2:(\text"10"+\text"2")^2=\text"100" :\text"144"$$

Answer: (a)

The relationship is x : (x - 2222).

As, $$\text"7584"-\text"2222"=\text" 5362."$$

$$ \text" Similarly", \text"4673"-\text"2222" = \text"2451" $$

Answer: (d)

The relationship is x : x⁵.

As, $$\text"3" ^5 = \text"243." \text" Similarly", \text"5"^5 = \text"3125" $$
