little pika has just learned addition
however she does not know how to carry.For example she can add 14 and 5 but she does not know how to add 14 and 7 how many pairs of consecutive integers between 1000 and 2000(both 1000 and 2000 included)pika can add

• 200 pairs.As she can add any number with 5,thereby dividing the numbers from 1000 to 2000,we will get 1000 numbers,out of which adding 5 with every result ,then we will get 200 pairs.
