Latest Ratio Based MCQ Objective Questions
Ratio Based Question 1:
Select the option that is related to the third number in the same way as the second number is related to the first number.
13 : 170 :: 15 : ?
Answer (Detailed Solution Below)
Ratio Based Question 1 Detailed Solution
The logic followed here is:
Logic: (1st number)2 + 1 = 2nd number.
Now,
For, 13 : 170
⇒ (13)2 + 1 = 169 + 1 = 170.
Similarly, for 15 ∶ ?
⇒ (15)2 + 1 = 225 + 1 = 226.
Hence, the correct answer is "Option 3".
Ratio Based Question 2:
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 2 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 3:
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 3 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 4:
Select the related number from the given alternatives.
444 : 21 :: 964 : ?
Answer (Detailed Solution Below)
Ratio Based Question 4 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 5:
2 : 11 :: 3 : ________
Answer (Detailed Solution Below)
Ratio Based Question 5 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.

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of :: ?
(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.)
X : 44 :: 72 : Y
Answer (Detailed Solution Below)
Ratio Based Question 13 Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: (1st number ÷ 2) + 10 = 2nd number.
X : 44 :: 72 : Y
For value of X.
X : 44
→ (X ÷ 2) + 10 = 44
→ (X ÷ 2) = 44 - 10
→ X = 34 × 2
→ X = 68
Now for value of Y.
72 : Y
→ (72 ÷ 2) + 10
→ 36 + 10
→ 46.
Thus, value of X is 68 and value of Y is 46.
Hence, the correct answer is "Option 4".
In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of :: ?
(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.)
X : 18.8 :: 21 : Y
Answer (Detailed Solution Below)
Ratio Based Question 14 Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: 1st number + 3.8 = 2nd number.
X : 18.8 :: 21 : Y
For, X
X : 18.8
→ X + 3.8 = 18.8
→ X = 18.8 - 3.8
→ X = 15
Now, for Y
21 : Y
→ 21 + 3.8 = Y
→ 24.8 = Y
Thus, Value of X is 15 and Value of Y is 24.8.
Hence, the correct answer is "Option 4".
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 15 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".
