Question

how many numbers between 100 to 300 divisible by 3​

Answer 1

Answer:

67

Explanation:

For these kinds of problems use formula,

L = A + (N - 1)*D,

Here, L is the last digit,

A is the first digit,

N is the number of digits in between, and D is the difference.

So, A = 102(after 99 this is the first number which is completely divisible by 3)

L = 300 (last number which is divisible by 3 completely in 100–300 range).

D = 3, and N we need to calculate.

So,

300 = 102+ (N - 1)* 3

300- 102 = (N-1)*3

198= (N-1) *3

66= N - 1

N = 66 +1 = 67.

So there are 67 Number which are exactly divisible by 3.
