Q3. A playground is in the shape of a rectangle. A sum of Rs. 1000 was spent to make the ground usable at the rate of 25 paise per sq. m. The breadth of the ground is 50m. If the length of the ground is increased by 20 m, what will be the expenditure in making this ground usable at the same rate?
Rs.1500
Rs.2250
Rs.1250
Rs.1000
Rs. 1800
Solution:
Area of ground = 1000/0.25 = 4000 m²
Length = 4000/50 = 80 m
New length = 80 + 20 = 100 m
New area = 100 × 50 = 5000 m²
So, expenditure = 5000 × 0.25 = Rs 1250

Directions (6 -10): Two equations I and II are given below. You have to solve these equations and give answer

Q6. I. x²-5 =0
II. 4y²-24y+35 = 0
if x<y
if x>y
if x ≤y
if x ≥y
if x = y or no relation can be established
Solution:

Q7. I. x²-5x-14=0
II. y²+7y+10 = 0
if x<y
if x >y
if x ≤y
if x ≥y
if x = y or no relation can be established
Solution:

Q8. I. 2x² + 9x + 9 = 0
II. 2y² + 17y + 36 = 0
if x<y
if x >y
if x ≤y
if x ≥y
if x = y or no relation can be established
Solution:
I. 2x² + 9x + 9 = 0
⇒ 2x² + 6x + 3x + 9 = 0
⇒ (x + 3) (2x + 3) = 0
⇒ x = –3, –3/2
II. 2y² + 17y + 36 = 0
⇒ 2y² + 8y + 9y + 36 = 0
⇒ (y + 4) (2y + 9) = 0
y = – 4, –9/2
x > y

Q9. I. 5x² + 29x + 20 = 0
II. 25y² + 25y + 6 = 0
if x<y
if x >y
if x ≤y
if x ≥y
if x = y or no relation can be established
Solution:
I. 5x² + 29x + 20 = 0
⇒ 5x² + 25x + 4x + 20 = 0
⇒ (x + 5) (5x + 4) = 0
⇒ x = –5, –4/5
II. 25y² + 25y + 6 = 0
⇒ 25y² + 15y + 10y + 6 = 0
⇒ (5y + 3) (5y + 2) = 0
⇒ y = – 3/5, –2/5
y > x

Q10. I. 3x² – 16x + 21 = 0
II. 3y² – 28y + 65 = 0
if x<y
if x >y
if x ≤y
if x ≥y
if x = y or no relation can be established
Solution:
I. 3x² – 16x + 21 = 0
⇒ 3x² – 9x – 7x + 21 = 0
⇒ (x – 3) (3x – 7) = 0
⇒ x = 3, 7/3
II. 3y² – 28y + 65 = 0
⇒ 3y² – 15y – 13y + 65 = 0
⇒ (y – 5)(3y – 13) = 0
⇒ y = 5, 13/3
y > x
