Answer: age of A is 55 yrs and age of B is 21yrs
Step-by-step explanation:
let the age of A be x and B be y
A/Q
x/11 = y/7+2
x/11-y/7=2
(7x-11y)/77=2
7x-11y=154—— eq1
also
2y=x-13
x=2y+13
by putting value of x in eq1
7(2y+13) -11y= 154
14y+91-11y=154
3y=154-91
y=63/3
y=21
therefore, x=2*21+13
x=42+13
x=55
Hence, age of A is 55 yrs and age of B is 21 yrs.
