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?
