How many multiples of 7 are there between 100 and 200?
100 और 200 के बीच 7 के कितने गुणज हैं?
Correct Answer:
The first number after 100 which is divisible by 7 is = 105
The last number before 200 which is divisible by 7 is = 196
We know an = a + (n - 1)d
196 = 105 + (n - 1)7
n - 1 = 13
n = 14
100 के बाद पहली संख्या जो 7 का गुणज है = 105
200 से पहले आख़री संख्या जो 7 का गुणज है = 196
हम जानते है की an = a + (n - 1)d
196 = 105 + (n - 1)7
n - 1 = 13
n = 14
