Explanation:
कितने 3 अंक संख्या 6 से विभाज्य हैं?
149
150
151
166
Answer: Option B
Required numbers are 102, 108, 114, ... , 996
This is an A.P. in which a = 102, d = 6 and l = 996
Let the number of terms be n. Then,
a + (n - 1)d = 996
102 + (n - 1) x 6 = 996
6 x (n - 1) = 894
(n - 1) = 149
n = 150.
8597 - ? = 7429 - 4358
7429 Let 8597 - x = 3071 -4358 Then, x = 8597 - 3071 ---- = 5526 3071 ----
सबसे छोटी प्रधान संख्या है:
1
2
3
4
(12345679 x 72) = ?
102 + (n - 1) x 6 = 996 6 x (n - 1) = 894 (n - 1) = 149 n = 150.
