a)242
b)54
c)216
d)108​

Answer 1

$\huge{ \boxed{ \bf{ \pink{An} \orange{sw} \pink{er...}}}}$

✦ Type of Question:

The above question is based on analogy relation between two numbers shown with a proportional symbol(:). The first two numbers is following certain rules and relations. Accordingly, we have to find the required number with the same relation.

━━━━━━━━━━━━━━━━━━━━

✦ Logic Behind the Question:

✏ Multiply the digits of first number and then, you will get the second number being relation with first number.

━━━━━━━━━━━━━━━━━━━━

✦ Solution:

Given, 1243 : 24

$\large{\rm{\purple{1 \times 2 \times 3 \times 4 = 24}}}$

And here, 24 is the second number.

Similarly,

$\large{\rm{\purple{9\times 1 \times 4\times 6 = 216}}}$

So, Our answer is $\large{\boxed{\rm{\red{216}}}}$

✏Option C.

✦ More questions to solve:

1) 5:525::7:? (Ans - 749)

Logic- First digit of resultant is a^1 and next digits are a^2. In this way, 7 : 749.

2) D:W::I:? (Ans - R)

Logic- The numerical position of the alphabets add upto 27. Similarly I is related to R, (9 + 18 = 27)

3) 8:9::64:? (Ans - 25)

Logic- The first number is the cube of a certain number and the second is the square of the successor of previous number. Like 8 is the cube of 2 and 9 is the square of 3. We already knew, 3 is the successor of 2.

✏In this way, you can solve different analogy questions based on numbers, alphabets, word relations, pictures etc.
