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 : ?

  1. 112
  2. 122
  3. 210
  4. 212

Answer (Detailed Solution Below)

Option 1 : 112

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 (6 - 1) = 12 5 = 60.

Similarly, for 16 ∶ ?

⇒ 16 x (16 / 2 - 1) = 16 (8 - 1) = 16 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 ::

  1. 9:81:70
  2. 19:361:342
  3. 17:288:272
  4. 16:225:239

Answer (Detailed Solution Below)

Option 2 : 19:361:342

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 : ?

  1. 31
  2. 41
  3. 24
  4. 29

Answer (Detailed Solution Below)

Option 1 : 31

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.

2 : 11 :: 3 : ________

  1. 30
  2. 45
  3. 33
  4. 31

Answer (Detailed Solution Below)

Option 1 : 30

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 : ?

  1. 17
  2. 22
  3. 18
  4. 19

Answer (Detailed Solution Below)

Option 3 : 18

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".

12: 60 :: 16 : ?

  1. 112
  2. 122
  3. 210
  4. 212

Answer (Detailed Solution Below)

Option 1 : 112

Ratio Based Question 11 Detailed Solution

Download Solution PDF

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 (6 - 1) = 12 5 = 60.

Similarly, for 16 ∶ ?

⇒ 16 x (16 / 2 - 1) = 16 (8 - 1) = 16 7 = 112.

Hence, the correct answer is "Option 1".

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

  1. 1)X = 7, Y = 110
  2. 2)X = 8, Y = 110 
  3. 3)X = 7, Y = 111
  4. 4)X = 8, Y = 111

Answer (Detailed Solution Below)

Option 1 : 1)X = 7, Y = 110

Ratio Based Question 12 Detailed Solution

The 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 : %

  1. 1) # = PRO, % = OQN
  2. 2) # = PRO, % = OQM
  3. 3) # = PRN, % = OQN
  4. 4) # = PRO, % = ORN

Answer (Detailed Solution Below)

Option 1 : 1) # = PRO, % = OQN

Given:

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.
