Answer 1

Hey!!!

Your Answer!!

Let's Think , a's Age Is x And b's Age Is y.

Now,

(x+20)+(y+20)=110

substituating value 1 in above equation

(3/4y+20)+(y+20)=110

3/4y+y+40=110

7y/4=70

y=40

x=3/4y=(3/4)40

x=30

20 year ago a's age was 30 and b's age was 40

today's their age is a's age =50

and b's age =60
