Arithmetic Progressions | Class 10 Maths | NCERT Solutions
Q1. | The sum of all odd integers between 2 and 100 divisible by 3 is |
A. 17 |
|
B. 867 |
|
C. 876 |
|
D. 786 |
Ans: 867
Explaination:Reason: The numbers are 3, 9,15, 21, …, 99
Here a = 3, d = 6 and an = 99
∴ an = a + (n – 1 )d
⇒ 99 = 3 + (n – 1) x 6
⇒ 99 = 3 + 6n – 6
⇒ 6n = 102
⇒ n = 17
Required Sum = \(\frac{n}{2}\)[a + an] = \(\frac{17}{2}\)[3 + 99] = \(\frac{17}{2}\) × 102 = 867
Explaination:Reason: The numbers are 3, 9,15, 21, …, 99
Here a = 3, d = 6 and an = 99
∴ an = a + (n – 1 )d
⇒ 99 = 3 + (n – 1) x 6
⇒ 99 = 3 + 6n – 6
⇒ 6n = 102
⇒ n = 17
Required Sum = \(\frac{n}{2}\)[a + an] = \(\frac{17}{2}\)[3 + 99] = \(\frac{17}{2}\) × 102 = 867
Q2. | If the numbers a, b, c, d, e form an A.P., then the value of a – 4b + 6c – 4d + e is |
A. 0 |
|
B. 1 |
|
C. -1 |
|
D. 2 |
Ans: 0
Explaination:Reason: Let x be the common difference of the given AP
∴ b = a + x, c = a + 2x, d = a + 3x and e = a + 4x
∴ a – 4b + 6c – 4d + e = a – 4 (a + x) + 6(a + 2x) – 4(a + 3x) + (a + 4x)
= a – 4a – 4x + 6a + 12x – 4a – 12x + a + 4x = 8a – 8a + 16x – 16x = 0
Explaination:Reason: Let x be the common difference of the given AP
∴ b = a + x, c = a + 2x, d = a + 3x and e = a + 4x
∴ a – 4b + 6c – 4d + e = a – 4 (a + x) + 6(a + 2x) – 4(a + 3x) + (a + 4x)
= a – 4a – 4x + 6a + 12x – 4a – 12x + a + 4x = 8a – 8a + 16x – 16x = 0
Q3. | If 7 times the 7th term of an A.P. is equal to 11 times its 11th term, then 18th term is |
A. 18 |
|
B. 9 |
|
C. 77 |
|
D. 0 |
Ans:
Explaination:Reason: We have 7a7 = 11a11
⇒ 7[a + (7 – 1)d] = 11[a + (11 – 1 )d]
⇒ 7(a + 6d) = 11(a + 10d)
⇒ 7a + 42d = 11a + 110d
⇒ 4a = -68d
⇒ a = -17d
∴ a18 = a + (18 – 1)d = a + 17d = -17d + 17d = 0
Explaination:Reason: We have 7a7 = 11a11
⇒ 7[a + (7 – 1)d] = 11[a + (11 – 1 )d]
⇒ 7(a + 6d) = 11(a + 10d)
⇒ 7a + 42d = 11a + 110d
⇒ 4a = -68d
⇒ a = -17d
∴ a18 = a + (18 – 1)d = a + 17d = -17d + 17d = 0
Q4. | If p, q, r are in AP, then p3 + r3 – 8q3 is equal to |
A. 4pqr |
|
B. -6pqr |
|
C. 2pqr |
|
D. 8pqr |
Ans: -6pqr
∴ 2q = p + r
⇒ p + r – 2q = 0
∴ p3 + r3 + (-2p)3 = 3 × p × r × -2q
[Using ifa + 6 + c = 0 ⇒ a3 + b3 + c3 = 3 abc]
⇒ p3 + r3 – 8q3 = -6pqr.
Explaination:
∵ p, q, r are in AP.∴ 2q = p + r
⇒ p + r – 2q = 0
∴ p3 + r3 + (-2p)3 = 3 × p × r × -2q
[Using ifa + 6 + c = 0 ⇒ a3 + b3 + c3 = 3 abc]
⇒ p3 + r3 – 8q3 = -6pqr.
