Question

18.The age of A is one-third of the age of B. After 15 years, the age of A will
be half of the age of B. Find their present ages.​

Answer 1

Answer:

Step-by-step explanation: let age of a be x and that of b be y

so,according to the question,

x=y/3        

after 15 yrs

x+15=(y+15)/2

so

x+15= y/3+15

y/3+15=(y+15)/2

2y+90=3y+45

y=45,x=45/3=15

so age of a is 45yrs and age of b is 15yrs
