Let me to know the calculation process.
Ans.101


Hi, and welcome to Gmat Club! Below is a solution for your problem:

\(# \ of \ multiples \ of \ x \ in \ the \ range = \frac{Last \ multiple \ of \ x \ in \ the \ range \ - \ First \ multiple \ of \ x \ in \ the \ range}{x}+1\).

For our original question we would have: \(\frac{2,000-1,000}{10}+1=101\).

Check this: totally-basic-94862.html?hilit=last%20first%20range%20multiple

Hope it helps.

My attempt:

1000 - 1100 -- 11
1110 - 1200 -- 10
1210 - 1300 -- 10

1X10 - 1(X+1)00 -- 10

X - 3, 4, 5, 6 ,7 ,8, 9.

Sum them up - 101.

In general the formula for any series where "d" is the increment or difference between two terms to find the nth term =
An= A1+ (n-1)d
Now we know An =2000
A1=1000
d=10
2000=1000+(n-1)10
=101

OR
Use this
( last -first )/ increment + 1

As already discussed, the method is [(Last-First)/Increment ]+1

If you are refering to mgmat by any chance, this is discussed in Chap4 of Number properties

Hi Bunuel, Thanks for the explanation. However, if the question would have been that how many multiples of 5 are there between -7 and 37, inclusive? Will we consider the last number to be 35 and the first number to be -5?

How many multiples of 5 are there between -7 and 37, inclusive?

The first multiple is -5 and the last multiple is 35, so the answer is (35 - (-5))/5 + 1 = 9:
-5, 0, 5, 10, 15, 20, 25, 30 and 35.

How many multiples of 5 are there between -7 and 37, inclusive?

The first multiple is -5 and the last multiple is 35, so the answer is (35 - (-5))/5 + 1 = 9:
-5, 0, 5, 10, 15, 20, 25, 30 and 35.

Thanks. I got it right. Now it's clear.
