Select the odd group of numbers. (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)

Option

By interchanging the given two signs and numbers which of the following equation will be correct?
 × and +, 6 and 4

Directions: In these questions, the relationship between different elements is shown in the statements. The statements are followed by conclusions. Study the conclusions based on the given statements and select the appropriate answer.

Statements:
 S ≤ L ≤ I = P ≥ E > R; L > Q

Conclusions: 
 I. P ≥ S     II. I > R
