Q8. The percentage of metals in a mine of lead ore is 60%. Now the percentage of silver is 3/4% of metals and the rest is lead. If the mass of ore extracted from the mine is 8000 kg, the mass (in kg) of lead is:
⇒Mass of metal in lead ore = 60% of 8000 = 4800 kg
⇒ Mass of silver in metal = (3/4)% of 4800=36 kg
⇒ Mass of lead in ore = 4800 – 36 = 4764 kg
Q9. Sum of area of a square and a rectangle is 644 sq. cm and perimeter of rectangle is 88 cm. If ratio of length to breadth of rectangle is 7 : 4, then find perimeter of square ?
11X = 44
X = 4
ℓ = 28, b = 16
Area of rectangle = 28 × 16 = 448 sq.
Area of square = 644 – 448 = 196 sq. cm
a² = 196
a = 14
perimeter of square = 4 × 14 = 56cm

Directions (11-15): In each of the following questions two equations are given. You have to solve the equations and Give answer –
Q11. I. 8x² + 6x = 5
II. 12y² – 22y + 8 = 0
⇒ 8x² + 10x – 4x – 5 = 0
⇒ (4x + 5) (2x – 1) = 0
⇒ x = ½, –5/4
II. 12y² – 22y + 8 = 0
⇒ 6y² – 11y + 4 = 0
⇒ 6y² – 3y – 8y + 4 = 0
⇒ (2y – 1) (3y – 4) = 0
⇒ y = 1/2, 4/3
y ≥ x
Q12. I. 17x² + 48x = 9
II. 13y² = 32y – 12
⇒ 17x² + 51x – 3x – 9 = 0
⇒ (x + 3) (17x – 3) = 0
⇒ x = 3/17, – 3
II. 13y² – 32y + 12 = 0
⇒ 13y² – 26y – 6y + 12 = 0
⇒ (y – 2) (13y – 6) = 0
⇒ y = 2, 6/13
y > x
Q13. I. 8x² + 26x + 15 = 0
II. 4y² + 24y + 35 = 0
⇒ 8x² + 20x + 6x + 15 = 0
⇒ 4x (2x + 5) + 3(2x + 5) = 0
⇒ (2x + 5) (4x + 3) = 0
⇒ x = – 5/2, –3/4
II. 4y² + 24y + 35 = 0
⇒ 4y² + 10y + 14y + 35 = 0
⇒ 2y (2y + 5) + 7 (2y + 5) = 0
⇒ (2y + 5) (2y + 7) = 0
⇒ y = –5/2, –7/2
x ≥ y
Q14. I. 6x² + 19x + 15 = 0
II. 24y² + 11y + 1 = 0
⇒ 6x² + 9x + 10x + 15 = 0
⇒ (2x + 3) (3x + 5) = 0
⇒ x = –3/2, –5/3
II. 24y² + 11y + 1 = 0
⇒ 24y² + 8y + 3y + 1= 0
⇒ (3y + 1) (8y + 1) = 0
⇒ y = –1/3, –1/8
y > x
Q15. I. 2x² + 11x + 15 = 0
II. 4y² + 22y + 24 = 0
⇒ 2x² + 6x + 5x + 15 = 0
⇒ (x + 3) (2x + 5) = 0
⇒ x = – 3, –5/2
II. 4y² + 22y + 24 = 0
⇒ 2y² + 11y + 12 = 0
⇒ 2y² + 8y + 3y + 12 = 0
⇒ (y + 4) (2y + 3) = 0
