Third row - 5, 6, ?
(
NOTE:
Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. Eg. 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)

Correct answer
14
Why this answer is correct
The logic followed here is:
Logic: 1st number + 2nd number + (2nd number ÷ 2) = 3rd number.
Now,
First row - 4, 6, 13
→ 4 + 6 + (6 ÷ 2)
→ 4 + 6 + 3 = 13.
Second row - 9, 8, 21
→ 9 + 8 + (8 ÷ 2)
→ 9 + 8 + 4 = 21.
Similarly, for Third row - 5, 6, ?
→ 5 + 6 + (6 ÷ 2)
→ 5 + 6 + 3 = 14.
Hence, the correct answer is "Option 1".
