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)

Answer 1

The pattern followed here is:

Logic:

(First number × 10) = Second number.

(Second number - 10) = Third number.

Let's check each option one by one.

Option 1) (6 - 60 - 50)

⇒ (6 × 10) = 60

⇒ (60 - 10) = 50

Option 2) (7 - 70 - 68)

⇒ (7 × 10) = 70

⇒ (70 - 10) = 60 ≠ 68

Option 3) (8 - 80 - 70)

⇒ (8 × 10) = 80

⇒ (80 - 10) = 70

Option 4) (9 - 90 - 80)

⇒ (9 × 10) = 90

⇒ (90 - 10) = 80

Hence, the correct answer is "(7 - 70 - 68)".
