Direction: In the following question two equation numbered I and II are given. Solve the equation and answer the question:
(i) 3x2 - 22x + 24 = 0
(ii) 3y2 - 20y + 25 = 0i. 3x2 - 22x + 24 = 0
⇒ 3x2 - 18x - 4x + 24 = 0
⇒ 3x (x - 6) - 4(x - 6) = 0
⇒ (x - 6) (3x - 4) = 0
⇒ x = 6 or 4/3
ii. 3y2 - 20y + 25 = 0
⇒ 3y2 - 15y - 5y + 25 = 0
⇒ 3y (y - 5) - 5(y - 5) = 0
⇒ (y - 5) (3y - 5) = 0
⇒ y = 5 or 5/3
When, x = 6, x > y for y = 5 and x > y for y = 5/3
And when x = 4/3, x < y for y = 5 and x < y for y = 5/3
∴ the relationship cannot be established between x and y2. What should come in place of question mark '?' in the following number series? 31 35 44 60 85 ?
