Let arunas age be '6x'
Let karuna's age be '5x'
6x-5x=5
x=5
Aruna's age=6x=6x5=30
Karuna's age = 5x5=25
Aruna's age after 20 years=30+20=50
Karuna's age after 20 years=25+20=45
Sum=50+45=95
Pls vote brainliest!
let the age of karuna be y
then according to ques. x/y=6/5......eq.1
according to ques.x-y=5......eq.2
from eq.2...x=5+y
putting this eq.1
we get,
5+y/y=6/5
cross multiplying,
6y=25+5y
6y-5y=25
y=5
putting this in eq.2
we get,
x-25=5
x=30
their present sum of ages=25+30=55
after 20 years 55+20=75
Answer=75
