Question

How many nu mbers are there between 1and100which are exactly divisible by 7?

Answer 1

14 Numbers are there .

Answer 2

Answer:

Step-by-step explanation:

or this we have to find how many numbers are there between 1 and 100 which are divisible by 7

100/7=14.28

so there are 14 numbers which are exactly divisible by 7 to leave a remainder of 4 number has to be of the form 7k+4

lets check for the 14th number 14th number=14*7+4=102 which is greater then 100 hence there are 13 numbers between 1 and 100 which leaves a remainder 4 when divided by 7

also if we put k=0 we get 4 which is also a number satisfying the criteria

total numbers=13+1=14
