Answers

1).a  From Eq Ⅰ and Ⅱ
y = 2
x = 7
x > y

2).e  Ⅰ. x2 + 7x + 7x + 49 = 0
x (x + 7) + 7 (x + 7) = 0
x = -7, -7
Ⅱ. y ( y + 9) = 0
y = 0, -9
Relation can’t be established

3).e  Ⅰ. 3x2 - 12x + 8x - 32 = 0
3x (x - 4) + 8 (x – 4) = 0
x =4, - (8 / 3)
Ⅱ. 2y2 +6y - y - 3 = 0
2y (y + 3) - 1 (y + 3) = 0
y = -3, (1 / 2)
Relation can’t be established

4).b  Ⅰ. 9x2 – 18 - 11x + 22 = 0
9x (x - 2) - 11 (x – 2) = 0
x =2, (11 / 9)
Ⅱ. 7y2 – 14y + 6y – 12 = 0
7y (y - 2) + 6 (y - 2) = 0
y = 2, - (6 / 7)
x ≥ y

5).c  Ⅰ. x2 + 7x + 7x + 49 = 0
x (x + y) + 7 ( x + 7) = 0
x = -7
Ⅱ. 2y2 - 8y – 9y + 36 = 0
2y (y – 4) – 9 (y – 4) = 0
y = 4, (9 / 2)
x < y

6). c 3√13824 + √1849 = 3√9261 + √?
Or, 24 + 43 = 21 + √?
Or, √? = 67 – 21 =46
? = 2116

7).c  (0.8) ÷ (0.2)2 × (0.6)2 = (2.4)2 × ?
Or, 5.76 × ? = (0.8 / 0.04) × 0.36 = 20 × 0.36 = 7.20
? = (7.20 / 5.76) = 1.25

8).d  ? = 7654.32 + 8962.81 + 3432.12 – 512.32 + 212.82 + 316.84
= 20066.59

9)a . 812 + 912 + 516 + 241 + 346 + 329 = 12 × ?
Or, 3156 = 12 × ?
Or, ? = (3156 / 12) = 263

10).b  ? = 4√1296 + 4√2401 + 4√6561 - 4√256
Or, ? = 6 + 7 + 9 – 4 = 18
