The number of four-digit integers which are greater than 1000 and divisible by both 2 and 3, but not by 5, is
Explanation:
Required numbers = Numbers which are divisible by both 2 and 3 - Numbers which are divisible by both 2, 3 and 5 = Numbers which are divisible by 6 - Numbers which are divisible by 30
Total number of 4 digit numbers = 9999 - 999 = 9000 Number of 4 digit numbers divisible by 6 = 9000/6 = 1500 Number of 4 digit numbers divisible by 30 = 9000/30 = 300
Required numbers = 1500 - 300 = 1200.
Hence, option (c).
