  Hi Rupali smile

We are to just pick 6 prime numbers, one each from the given ranges (i.e. 0 to 10, 11 to 20, 21 to 30, 31 to 40, 41 to 50 and 51 to 60) such that difference between two consecutively selected prime numbers is at least 10.

Also as sum of all 6 prime numbers is even, so each of six prime numbers must be ODD.

It can be easily checked that selected prime numbers can be: 3-13-23-37-47-59 only.

Thus required answer is (c) 17. smile
