Read Solution (Total 1)
-
- 100 < n < 200,
No of Even integers divisible by 9 = 198-108/18 = 5
No of even integers divisible by 7 = (196-112)/14 = 6
No of even integers divisible by 9 and 7 = 1 [126]
Total no of even integers divisible by either 9 or 7 = 5+6-1 =10
Total no of even integers divisible by neither 9 nor 7 = 48 -10 = 38 - 11 years agoHelpfull: Yes(0) No(1)
