Question

Find the result of substracting the sum of all integers between 15 and 35 from the sum of all integers from 20 to 30

Answer 1

Answer:

First set is between 20 and 30 so we don't count 20 and 30

Whereas the second set is from 20 till 30

When we know this we need not calculate the sum as the difference is just the numbers not taken in consideration in first case that is 30 and 20

Hence the required answer is 20+30=50
