How many natural numbers are there between 43 and 200 which are exactly divisible by 6?  Select:  A) 26  B) 25  C) 24  D) 22  E) 23

Rationale: "43 / 6 = 7 , remainder = 1 . hence 5 more should be added to 43 to get the minimum number divisible by 6 between 43 and 200 . = > minimum number divisible by 6 between 43 and 200 = 43 + 5 = 48 200 / 6 = 33 , remainder = 2 . hence 2 should be decreased from 200 to get the maximum number divisible by 6 between 43 and 200 . = > maximum number divisible by 6 between 43 and 200 = 200 - 2 = 198 hence , natural numbers numbers divisible by 6 between 43 and 200 are 48 , 54 , 60 , . . . 198 this is arithmetic progression with a = 48 , d = 6 , l = 198 number of terms = ( l − a ) / d + 1 = ( 198 − 48 ) / 6 + 1 = 150 / 6 + 1 = 25 + 1 = 26 answer is a"
