Answer: Option C

Explanation:

মনেকরি,
5 বছর পূর্বে পিতার বয়স = 5x বছর
এবং পুত্রের বয়স = x বছর
.:. বর্তমানে পিতার বয়স = (5x + 5) বছর
বর্তমানে পুত্রের বয়স = (x + 5) বছর
প্রশ্নমতে, 5x + 5 + 2 = 3 (x + 5 + 2)
⇒ 5x + 7 = 3(x + 7)
⇒ 5x + 7 = 3x + 21
⇒ 2x = 14
⇒x = 7
.:. বর্তমানে পিতার বয়স 5 × 7 + 5 = 40 বছর
বর্তমানে পুত্রের বয়স = 7 + 5 = 12 বছর
.:. পিতা ও পুত্র = 40 : 12 = 10 : 3

C. 4
D. 4.5

View Answer	Favorite Question

Answer: Option B

Explanation:

5a ^ 2 - 4a - 3 - 3(a ^ 2 + a + 4) = 0 5a ^ 2 - 4a - 3 - 3a ^ 2 - 3a - 12 = 0 2a ^ 2 - 7a - 15 = 0 → 2a ^ 2 - 10a + 3a - 15 = 0 a - 5 = 0 a = 5
* 2a(a - 5) + 3(a - 5) = 0
Rightarrow (a - 5)(2a + 3) = 0
2a + 3 = 0
a = - 3/2
5 + (- 3/2) = 5 - 3/2 = (10 - 3)/2 = 7/2 = 3.5
