234 : 24 :: 456 : ?
Answer (Detailed Solution Below)
Ratio Based Question 4 Detailed Solution
The logic followed here is:
Logic: The second number is the product of the individual digits of the first number.
logic:
For 234 : 24
→ Digits are 2, 3, 4
→ Product of digits = 2 × 3 × 4 = 25
→ 6 × 4 = 24
Similarly,
For 456 : ?
→ Digits are 4, 5, 6
→ Product of digits = 4 × 5 × 6 = ?
→ 20 × 6 =120
Hence, the correct answer is "Option 1".
Ratio Based Question 5:
Select the option that is related to the third term in the same way as the second term is related to the first term.
5 : 25 :: 9 : ?
Answer (Detailed Solution Below)
Ratio Based Question 5 Detailed Solution
The logic followed here is:
Logic: Second number = (First number)²
For 5 : 25
→ (5)² = 25
Similarly,
For 9 : ?
→ (9)² = 81
→ The missing number is 81.
Hence, the correct answer is "Option 3".

Find a pair that is similar to 2401 ∶ 343.
Answer (Detailed Solution Below)
Ratio Based Question 10 Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: x4 : x3
2401 ∶ 343.
74 : 73
Similarly,
Option 2) 256 ∶ 64
44 : 43
Thus, 256 ∶ 64 follow same logic.

961:2::721: ?
Answer (Detailed Solution Below)
Ratio Based Question 11 Detailed Solution
Download Solution PDFThe logic followed here is:
961:2
9 - (6 + 1) = 2
9 - 7 = 2
2 = 2 (LHS = RHS)

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 12 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".
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 13 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".
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 14 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.
Similarly, for 16 ∶ ?
⇒ 16 x (16 / 2 - 1) = 16 x (8 - 1) = 16 x 7 = 112.
Hence, the correct answer is "Option 1".
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 15 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".
