For the year 2016, Sid has taken a New Year resolution for being very fit. Therefore, starting with January 1, 2016, he has decided to go for swimming every second day gym every third day and jogging every fifth day. The three activities are very energy intensive and require, respectively, 130 calories, 140 calories, 110 calories. If January 1, 2016 happens to be a Sunday,then, on how many days, does Sid not go for any of the three activities?

a) 95   b) 96   c) 97   d) 98




P.S. Considering he doesn't go to any of the activities on 1st jan. I am getting the answer 70 days , i.e, all the prime numbers between 1 to 366 leaving 2,3 and 5.But that's not given in the option.HELP!!

Find the arithmetic mean of the series

The question doesn't specify the value of n ,i.e,whether it is natural number or something else.
If we take n=3 for 3rd term it comes out to be 2^3 and not 2^7.Help.
