Question

Sum of present age of suresh and mahesh is 51 after3yrs ratio of age of suresh and mahesh is 9:10

Answer 1

ANWSER-24 AND 27 respectively

Step-by-step explanation:

case 1-

present:-

let the age of suresh be x

let the age of mahesh be y

According to the problem:

x+y=51--------------(eqn.i)

case 2-

after 3 yrs:-

the age of suresh be 3+x

the age of mahesh be 3+y

According to the problem:

3+x:3+y=9:10

3+x÷3+y=9÷10

30+10x=27+9y

10x-9y=-3 --------(eqn.ii)

Multiplying equation i with 10 we get:-

10x+10y=510--------(eqn.iii)

subtracting eqn.ii and iii we get:-

10x+10y=510

-10x+9y=+3

------------------

19y=513

y= 27

substituting the value of y in eqn.i we get:-

x+y=51

x+27=51

x=51-27

x=24

Therefore suresh is 24 years old and mahesh is 27 years old.....

hope so it helps u;)
