| Answer: Option A |
|
|
| Explanation: |
|
Let Sn = (1 + 2 + 3 + ... + 45)
This is an A.P. in which a = 1, d = 1, n = 45 and l = 45
Sn = |
n |
(a + l) |
= |
45 |
x (1 + 45) = (45 x 23) = 1035 |

| Answer: Option D |
|
|
| Explanation: |
|
Required numbers are 10, 15, 20, 25, ..., 95
This is an A.P. in which a = 10, d = 5 and l = 95.
tn = 95 ==> a + (n - 1)d = 95
10 + (n - 1) x 5 = 95
(n - 1) x 5 = 85
(n - 1) = 17
n = 18
Requuired Sum = |
n |
(a + l) |
= |
18 |
x (10 + 95) = (9 x 105) = 945. |
