i)Find the sum of those integers between 1 and 500 which are multiples of 2 as well as of 5.
ii)Find the sum of those integers from 1 to 500 which are multiples of 2 as well as of 5 .
iii)Find the sum of those integers from 1 to 500 which are multiples of 2 or 5.
i)
ii)
iii)
The sum of integers from 1 to 500 which are multiples of 2 or 5 = sum of integers which are multiples of 2 + sum of integer which are multiple of 5 - the sum of integer which is multiple of 10
(we subtract the sum of integers multiple of 10 because those integers are multiples of both 2 and 5 )
= 88000 - 12750 = 75250
