Answer:
number of integer from 5 to 300 is divisible by 5 is 300/5=60.
5/5=1 number lie
10/5=2 number lies
…..
300/5=60
if we take from 0 to 300 then 61 number divisible.because 0 is also divisible by 5 (0/5=0).
number of integer from 5 to 700 is divisible by 5 is 700/5=140.
if inclusive both number 300 and 700.its mean number of integer divisible by 5 from 5 to 295 subtract from number of integer divisible by 5 from 5 to 700.
so number of integer from 5 to 295 is divisible by 5 is 295/5=59.
number of integer from 5 to 700 is divisible by 5 is 300/5=140.
answer is 140–59=81(if 300 and 700 both inclusive ).
if exclusive both number 300 and 700.its mean number of integer divisible by 5 from 5 to 300 subtract from number of integer divisible by 5 from 5 to 695.
answer is 139–60=79(if 300 and 700 both exclusive).
