The number must be 57. It satisfies both the conditions as well. The digit at tens place that is 5 and the digit and units place ie 7 both are consecutive prime numbers and their sum 5+7 = 12 have 3 and 4 both as its factors. Means 12 is the multiple of both 3 and 4. So 57 must be the answer.
Thank you.
