40 is related to 53 following certain logic. Following the same logic, 8 is related to 13. To which of the following numbers is 68 related, following the same logic? (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.)
85
To solve this logical reasoning question, we need to identify the pattern or logic applied to relate the numbers. The relationship given in the problem is as follows:
Let's deduce the logic behind how these numbers are related:
Now, identify consistent logic applicable to both pairs:
To determine the number related to 68 using similar logic, observe the pattern in the earlier examples. Here, we will use the same increase amount:
Hence, the number to which 68 is related, following the same logic, is 85. Now let's check against the options given:
Therefore, the correct option is 2.85.
21 is related to 220 by certain logic. Following the same logic, 72 is related to 781. To which of the following is 27 related, following the same logic?
(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.)
Three of the following numbers are alike in a certain way and one is different. Pick the odd one out. (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.)

Select the correct mirror image of the given figure when the mirror is placed at MN as shown below.

In a certain code language, A + B means 'A is the husband of B', A - B means 'B is the mother of A', A x B means 'B is the sister of A', and A ÷ B means 'A is the daughter of B'. Based on the above, how is Q related to T if 'P + Q x R - S ÷ T'?
Identify the figure given in the options which when put in place of ? will logically complete the series.
Seven people A, B, C, D, E, F and G, scored different marks (out of 100) in an exam. G scored the lowest marks. B scored second highest marks, which were 80. A scored 72. E scored more than F but less than C. Marks scored by C were a multiple of 11 and less than 70. The sum of marks scored by C and F was 120. What is the score of F?
Select the figure from among the given options that can replace the question mark (?) and logically complete the series:
