Solution
The correct option is B 67,8
The given series 55, 168, 57, 120, 60, 80, 62, 48, 65, 24, ?, ? is a combination of two series.
1st series: 55, 57, 60, 62, 65, ? 2nd series: 168, 120, 80, 48, 24, ?
In the 1st series. each term increases by 2 and 3 alternatively.
In the 2nd series, each term is decreased by multiple of 8 starting from 48, 40, 32, 24, 16.
Clearly, 65 + 2 = 67 and 24 - 16 = 8
Hence, option (B) is the correct answer.
