Solution
S1. Ans.(a)
Sol.
I. 6x² + 7x + 2 = 0
6x² + 3x + 4x + 2 = 0
3x (2x + 1) + 2 (2x + 1) = 0
x = (–1)/2, (–2)/3
II. 3y² + 8y + 5 = 0
3y² + 5y + 3y + 5 = 0
y(3y + 5) + 1 (3y + 5) = 0
y=–1,(–5)/3
x > y
S2. Ans.(d)
Sol.
I. 7x² – 23x + 6 = 0
7x² – 21x – 2x + 6 = 0
7x (x – 3) – 2 (x – 3) = 0
x=3,2/7
II. y² – 7y + 12 = 0
y² – 3y – 4y + 12 = 0
y(y – 3) – 4 (y – 3) = 0
y = 3, 4
y ≥ x
S3. Ans.(e)
Sol.
I. 5x² + 13x – 6 = 0
5x² + 15x – 2x – 6 = 0
5x (x + 3) – 2 (x + 3) = 0
x=2/5, –3
II. 2y² + 13y – 7 = 0
2y² + 14y – y – 7 =0
2y ( y + 7) – 1 (y + 7) = 0
y = –7, 1/2
No relation
S4. Ans.(c)
Sol.
I. 4x + 3y = 4 …(i)
II. 6x + 5y = 8 …(ii)
Multiplying (i) by 5 and (ii) by 3 & subtracting (ii) from (i), we get
x = –2
put x=-2 in (i), we get
y = 4
y > x
S5. Ans.(a)
Sol.
I. x² – 19x + 88 = 0
x² – 11x – 8x + 88 = 0
x (x – 11) – 8 (x – 11) = 0
x = 8, 11
II. y² + y – 56 = 0
y² + 8y – 7y – 56 = 0
y (y + 8) – 7 (y + 8) = 0
y = 7, – 8
x > y
S6. Ans.(d)
Sol.
S7. Ans.(b)
Sol.
S8. Ans.(a)
Sol.
S9. Ans.(c)
Sol.
S10. Ans.(e)
Sol.
S11. Ans.(b)
Sol.
1782 ÷ 54 + 456 – 2346 × 1 = ? × 3
⇒ 33 + 456 – 2346 = ? × 3
⇒ – 1857 = ? × 3
⇒ ?=(–1857)/3
= –619
S12. Ans.(c)
Sol.
(575+7511 –2769)÷(76×1+675 –342)=√(?)
= 5317÷409=√(?)
⇒ ? = (13)^2 = 169
S13. Ans.(a)
Sol.
[(√(3844×9))÷(27)^(1/3) ]×23=?^2+337
⇒[(62×3)÷3]×23=?^2+337
⇒ 1426 – 337 = ?²
⇒ ? = √1089
= 33
S14. Ans.(d)
Sol.
=√((96)×12÷18+26 –9) = (65 –?)% of 36
⇒9=((65 –?))/100×36⇒(65 –?)=(9×100)/36
⇒ ? = 65 – 25 = 40
S15. Ans.(a)
Sol.
12×√225+1212 –(1053÷9) = ?
⇒ 1392 – (117) = ?
⇒ ? = 1275
S16. Ans.(c)
Sol.
3.5 × 18 – (?)² = 36 + 2
63 – 38 = (?)²
25 = (?)²
? = 5
S17. Ans.(b)
Sol.
?=2975/1190
? = 2.5
S18. Ans.(b)
Sol.
(25÷4×6)/3= ?
? = 12.5
S19. Ans.(c)
Sol.
(390 + 310 – 225) 4 = ?
(700 – 225) 4 = ?
475 × 4 = ?
? = 1900
S20. Ans.(e)
Sol.
9 × 25 + 1225 + 150 = (?)²
225 + 1225 + 150 = (?)²
? = √1600
? = 40
