Question

five years ago the average age of monu's age that time and ninu's age that time will be 17 years. five years from now if the ratio of monu's age to ninu's age that time was 8:5, What is monu's present age?

Answer 1

Answer:

Monu=28 years

Step-by-step explanation:

5 years ago:Monu is x-5

                    Ninu is y-5

now:Monu is x

        Ninu is y

5 years later:Monu is x+5

                     Ninu is y+5

∴ (x-5)+(y-5)÷2=17

hence:(x-5)+(y-5)=34

∴x+y=(x-5)+(y-5)+10=34+10

=44

(x+5)+(y+5)=34+20 years

=54

(x+5)=8

(y+5)=5

8+5=13

∴13=54

   8=z

z=33

(x+5)=33

x=33-5

x=28

monu=28 years
