Question

how many numbers are ther btw 1 to 500 which are divisible by 3 and 5​

Answer 1

Answer:

33 to 34 numbers

Step-by-step explanation:

first you can write which are divisible by 5 search the numbers like 15, 30, 45, like

Answer 2

smallest number between 1 to 500 which is divisible by 3 = 3

largest number between 1 to 500 which is divisible by 3 =498

so, a=3, d=3, last digit or l or an=498

as we know,

an=a+(n-1)d

498=3+(n-1)3

498-3=(n-1)3

495/3=n-1

165+1=n

166=n

so 166 numbers are divisible by 3 btw 1 to 500

smallest number between 1 to 500 which is divisible by 5= 5

largest number between 1 to 500 which is divisible by 5= 495

so, a=5, d=5, last digit or l or an=495

as we know,

an=a+(n-1)d

495=5+(n-1)5

495-5=(n-1)5

490/5=n-1

98+1=n

99=n

so 99 numbers are divisible by 5 btw 1 to 500
