Explanation:Odd numbers from 3 to 36 are : 3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33 and 35
Total number of these odd numbers = 17 and
Total number of numbers from 3 to 36 = (36 - 3) + 1 = 34
Remaining number = 34 - 17 = 17

Explanation: Total of the numbers from 4 to 65 = (65 - 4) + 1 = 62
Numbers which are removed are 9 ,16,18,25,27,36,45,49,54,63 and 64.
Total of these numbers = 11
Remaining number = 62 - 11 = 51

Explanation: On arranging numbers from 7 to 59,
which are divisible by 3, in descending order , we get
57,54,51 , 48, 45, 42, 39, 36, 33, 30, 27, 24, 21, 18, 15, 12 and 9.
36 is the number which will be at 10th place from bottom.
