Study the given pattern carefully and select the number that can replace the question mark (?) in it.
First row- 14, 4, 31 Second row- 38, 10, 79 Third row- 30, 8, ?
(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)
Explanation:
Here the logic is for each row:
T1 ÷ 4 + 0.5 = T2 and T2 × 8 - 1 = T3
Hence,
Row 1: 14/4 ÷ 0.5 = 4 and 4 × 8 - 1 = 31 Row 2: 38/4 ÷ 0.5 = 10 and 10 × 8 - 1 = 79
⇒ Row 3: 30/4 ÷ 0.5 = 8 and 8 × 8 - 1 = 63
Hence, option (c).
