b)y^2 -24y + 119 = 0x>yxx=y or relationship cannot be establishedx is less than or equal to yx is greater than or equal to yOption C

x=7,14

y=7,17 - Six year ago,the sum of ages of Akansha and Banya was 64 years.The age of Akansha after 8 years and age of Banya after 14 years will be the same.Then what is the age of Akansha ,15 years from now?
56 years50 years54 years60 yearsNone of theseOption A

Let the present age of Akansha=x

Present age of Banya=76-x

x+8=76-x+14

x=41

Therefore,age of Akansha 15 years from now=41+15=56 years - The perimeter of rectangle X is 96 cm,where the difference in lenght and breadth is 8 cm.Area of rectangle Y is 30% more than the area of rectangle X.Find the area of rectangle Y?
750728740752None of theseOption B

Let breadth=x

Lenght=x+8

Perimeter=2*(x+x+8)

2x+8=48

x=20

x+8=20+8=28

Area of rectangle X=20*28

Area of rectangle Y=130% of 20*28

=728 sq cm - The salaries of X,Y and Z are in ratio of 5:4:6. If increments of 20%,30% and 25% are allowed respectively in their salaries,then what will be the new ratio of their salaries?

=5*120:4*130:6*125

=60:52:75 - Xylo is 48 years old.If Xylo’s age is 20% greater than that of Yash then by how much percent is Yash’s age less than Xylo’s age?
13.33%16.66%15%14%None of theseOption B

Age of Xylo=120% of age of Yash

48=120% of Yash

Yash=(48*100)/120=40
