In each of the given number-clusters, the number on the right side of = (the equal to sign) is calculated by performing certain mathematical operations on the two numbers on the left of = (the equal to sign). All three number-clusters follow the same pattern. Select the number from among the given options that can replace the question mark (?) in the third number-cluster.
12, 33 = 57
10, 28 = 48
14, 39 = ?
The logic is- 12 x 2 + 33 = 57 10 x 2 + 28 = 48 14 x 2 + 39 = 67
