S3. Ans.(a)
Sol. P      Q
      5x    4x
20x^2=720
x^2=36
x = 6
P = 5 × 6 
= 30 
S4. Ans.(d)
Sol. smaller sister = x
Jasmine’s age = 3x
3x^2=300
x^2=100
x=10
Jasmine’s age = 3 × 10 = 30 
S5. Ans.(a)
Sol. Ananya = x
Ajay = 2x – 4 
x(2x – 4) = 240 
2x^2-4x=240
x^2-2x-120=0
x^2-12x+10x-120=0
x(x-12)+10(x-12)=0
x = 12 
S6. Ans.(c)
Sol. A = 2x
B = 3x
(2x+12)/(3x+12)=5/6
12x+72=15x+60
3x=12
x = 4 
Total = 11x 
= 11 × 4 
= 44 years 
S7. Ans.(a)
Sol. P : Q
        4 : 3
(3x+10)/(2x+10)=4/3
9x + 30 = 8x + 40 
x = 10 
P     Q
40, 30
S8. Ans.(d)
Sol. Akhil = 2x 
Vineeta = x 
(2x – 12) = 5(x – 12) 
2x – 12 = 5x – 60 
3x = 48 
x = 16 
Akhil = 2 × 16 
= 32 years 
S9. Ans.(a)
Sol. Daughter = x
Mother = 8x 
6(x + 4) = (8x + 4) 
6x + 24 = 8x + 4
2x = 20 
x = 10 
Daughter = 10 + 4 
= 14 years 
S10. Ans.(d)
Sol. A = 5x
B = 8x 
(5x + 4)/(8x + 4)=2/3
15x + 12 = 16x + 8 
x = 4
B = 8 × 4 = 32
