Logical Reasoning Question 1:
When a number is subtracted from the square of 25, it becomes 124 times of the number. Find the number.
Answer (Detailed Solution Below)
Logical Reasoning Question 1 Detailed Solution
Let the number be a.
According to question:
252 - a = 124a
⇒ 625 - a = 124a
⇒ 625 = 124a + a
⇒ 625 = 125a
⇒ 625/125 = a
⇒ 5 = a
Hence, '5' is the correct answer.

How many triangles are there in the given figure?
Answer (Detailed Solution Below)
Logical Reasoning Question 6 Detailed Solution
Download Solution PDFHence there are "24" triangles in the figure.
First let's count the sections of the given triangle and then add them, then that is the number of triangles.
Lines originating from the top vertex are dividing the triangle into 4 parts. And naming the parts as 1, 2, 3, and 4. (Upper and bottom figure)
Then adding these parts separately we get,
Number of triangles (Upper)= 1 + 2 + 3 + 4 = 10.
Number of triangles (Upper and bottom) = 2 × 10 = 20.
Number of triangles = 4
Thus, total number of triangles = 20 + 4 = 24.

Logical Reasoning Question 8 Detailed Solution
Download Solution PDFHere all the polygon are of odd number of sides except hexagone.
Hendecagon is a polygon of 11 sides, Heptagon is a polygon of 7 sides and Pentagon is a polygon of 5 sides.
Only Hexagon is an odd one here as it has even number of sides i.e. 6 sides.
Hence, option 2 is the correct answer.

The figure will appear when it is opened as follows:
Hence, "Option - (3)" is the correct answer.
Select the option that is related to the fifth number in the same way as the second number is related to the first number and fourth number is related to third number.
(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 /deleting /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)
139 : 228 :: 122 : 211 :: 2 : ?
Answer (Detailed Solution Below)
Logical Reasoning Question 13 Detailed Solution
Download Solution PDFThe pattern followed here is:
Logic: Second number - First number = 89
1) 139 : 228
⇒ 228 - 139 = 89
And,
2) 122 : 211
⇒ 211 - 122 = 89
Similarly,
3) 2 : ?
⇒ X - 2 = 89
⇒ X = 89 + 2
⇒ X = 91
Hence, the correct answer is "91".
Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row - 67, 25, 101
Second row - 55, 17, 97
Third row - 45, 19, ?

Answer (Detailed Solution Below)
Logical Reasoning Question 14 Detailed Solution
Download Solution PDFThe logic followed here is:
(First number × 3) - (Second number × 4) = Third number
First row - 67, 25, 101 → (67 × 3) - (25 × 4) = 201 - 100 = 101
Second row - 55, 17, 97 → (55 × 3) - (17 × 4) = 165 - 68 = 97
Similarly,
Third row - 45, 19, ? → (45 × 3) - (19 × 4) = 135 - 76 = 59
Hence, option 4) is the correct answer.
Select the number-pair from the given options where the first number is NOT related to the second number as in the given number-pair:
4 : 8
Answer (Detailed Solution Below)
Logical Reasoning Question 15 Detailed Solution
Download Solution PDFImportant Points
- NOT Related means "We have to find a pair that is different from the given pair."
- The logic followed here is: Second number = First number × (First number ÷ 2)
- Given: 4 : 8 ⇒ 4 × (4 ÷ 2) = 4 × 2 = 8
- 8 : 32 ⇒ 8 × (8 ÷ 2) = 8 × 4 = 32
- 2 : 2 ⇒ 2 × (2 ÷ 2) = 2 × 1 = 2
- 3 : 9 ⇒ 3 × (3 ÷ 2) = 3 × 1.5 = 4.5 ≠ 9
- 6 : 18 ⇒ 6 × (6 ÷ 2) = 6 × 3 = 18
Hence, "option 3" is the correct answer.
