Latest Ratio Based MCQ Objective Questions
Ratio Based Question 1:
Select the option at the place of (?) that is related to the third number in the same way as the second number is related to the first number.
12: 60 :: 16 : ?
Answer (Detailed Solution Below)
Ratio Based Question 1 Detailed Solution
The logic followed here is:
Logic: Second number = First number x (First number / 2 - 1).
Now,
For, 12 : 60
⇒ 12 x (12 / 2 - 1) = 12 x (6 - 1) = 12 x 5 = 60.
Similarly, for 16 ∶ ?
⇒ 16 x (16 / 2 - 1) = 16 x (8 - 1) = 16 x 7 = 112.
Hence, the correct answer is "Option 1".
Ratio Based Question 2:
Choose the correct option whose group numbers follow the same pattern as that of the pattern in two groups of numbers given in the question.
11 : 121 : 110 :: 15 : 225 : 210 ::
Answer (Detailed Solution Below)
Ratio Based Question 2 Detailed Solution
The logic followed here is:
11 : 121 : 110 → 121 - 11 = 110
And,
15 : 225 : 210 → 225 - 15 = 210
So, checking each option one by one:
Option 1) 9:81:70 → 81 - 9 = 72 ≠ 70
Option 2) 19:361:342 → 361 - 19 = 342
Option 3) 17:288:272 → 288 - 17 = 271 ≠ 272
Option 4) 16:225:239 → 225 - 16 = 209 ≠ 239
Hence, "Option 2" is the correct answer.
Ratio Based Question 3:
Select the related number from the given alternatives.
444 : 21 :: 964 : ?
Answer (Detailed Solution Below)
Ratio Based Question 3 Detailed Solution
The logic followed here is:
444 : 21
√(444 - 3) = 21
√(441) = 21
21 = 21 (LHS = RHS)
Similarly,
964 : ?
√(964 - 3) = ?
√(961) = ?
31 = ?
Hence, "Option 1" is the correct answer.
Ratio Based Question 4:
2 : 11 :: 3 : ________
Answer (Detailed Solution Below)
Ratio Based Question 4 Detailed Solution
The logic followed here is:
2 : 11
23 + 3 = 11
8 + 3 = 11
11 = 11 (LHS = RHS)
Similarly,
3 : __
33 + 3 = ?
27 + 3 = ?
30 = ?
Hence, "Option 1" is the correct answer.
Ratio Based Question 5:
Choose the correct alternative for the following:
258 : 16 :: 326 : ?
Answer (Detailed Solution Below)
Ratio Based Question 5 Detailed Solution
The logic followed here is:
Logic: Square root of (first number - 2) = second number.
Now,
For, 258 : 16
⇒ \(\sqrt{258 - 2}\) = \(\sqrt{256}\) = 16. This matches the given pair.
Similarly, for 326 : ?
⇒ \(\sqrt{326 - 2}\) = \(\sqrt{324}\) = 18.
Hence, the correct answer is "Option 3".

Answer (Detailed Solution Below)
Ratio Based Question 11 Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: Second number = First number x (First number / 2 - 1).
Now,
For, 12 : 60
⇒ 12 x (12 / 2 - 1) = 12 x (6 - 1) = 12 x 5 = 60.

Of the following pairs of numbers, the second number is obtained by performing certain mathematical operations on the first number. Now what numbers should come at the position of X and Y so that the pattern followed by the numbers written to the left of :: is the same as the numbers written to the right of ::. (Note: Mathematical operations should be performed without separating the denominators of whole numbers. For example, 13 - Mathematical operations such as addition/subtraction/multiplication can be performed on the number 13. It is not allowed to separate the denominators 1 and 3 of 13 and perform arithmetic operations on 1 and 3.) X ∶ 47 ∶∶ 16 ∶ Y
Answer (Detailed Solution Below)
Ratio Based Question 12 Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: First number × 7 - 2 = Second number
(X : 47) to find X:
→ X × 7 - 2 = 47
→ X × 7 = 47 + 2
→ X × 7 = 49
→ X = 49 ÷ 7
→ X = 7
Similarly,
(16 : Y):
→ 16 × 7 - 2 = Y
→ 112 - 2 = Y
→ Y = 110
Thus, X = 7, Y = 110.
Hence, the correct answer is 'Option 1".
Which of the following characters must replace # and % in ' so that the pattern and relationship followed between the character pair on the left side of :: is the same as that on the right side of ::? # : LNK :: SUR : %
Answer (Detailed Solution Below)
Ratio Based Question 13 Detailed Solution
Download Solution PDFGiven:
Logic: Letter - 4.
# to LNK:
Let # be PQR
P to L: -4
R to N: -4
O to K: -4
Now apply this to SUR to find %:
S (19) - 4 = 15 (O)
U (21) - 4 = 17 (Q)
R (18) - 4 = 14 (N)
% = OQN.
Thus, # = PRO, % = OQN
Hence, the correct answer is "Option 1".
Replace the question mark with an option that follows the same logic applied in the first pair.
17:4::86: ?
Answer (Detailed Solution Below)
Ratio Based Question 14 Detailed Solution

(1 + 7) ÷ 2 = 4
8 ÷ 2 = 4
4 = 4 (LHS = RHS)
Similarly,
86: ?
(8 + 6) ÷ 2 = ?
14 ÷ 2 = ?
7 = ?
Hence, "Option 2" is the correct answer.
