1.	How many multiples of 4 are there in between 10 and 250
Answer» the numbers between\xa010\xa0and\xa0250\xa0which are multiple of\xa04\xa0are\xa012,16,20,...,248.\xa0This is an AP with first term\xa0a=12, common difference\xa0d=4.Let there be\xa0n\xa0terms in this AP, thenan\u200b=248⇒a+(n−1)d=248⇒12+(n−1)×4=248⇒(n−1)=59⇒n=60
