Select the number from among the given options that can replace the question mark (?) in the following series.
13, 39, 65, 91, 117, ?
The correct answer is D
34 × 5 × 2 ÷ 6 + 7 × 5 + 13 = (?)× 6 – 754
15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
(7 ÷ 0.125) x (10 ÷ 10/3 ) = ?
15(2/9) + 11(2/9) + 17(1/9) + 13(4/9) = ?
120% of 25 + 80 X 2 = ?2 - 6
116 x (2/3)% of 420 + 666 x (2/3)% of 186 = 457 x (1/7)% of 126 + 555 x (5/9)% of 198 + ?
2/5 of 3/4 of 7/9 of 7200 = ?
4567.89 - 567.89 - 678.89 = ?
(72× 52+ 1555 )/(79+60) = 2000 ÷ ?
25% of 60 × 15% of 120 = 30% of (?)
