Question

Ram is 3 years younger to his sister rohini if the sum of their ages is 37 years what are their present ages

Answer 1

Answer:

So their Present ages are Ram 17 years and Rohini 20 years

Step-by-step explanation:

Let the age of Ram is x years

And age of Rohini is y years

According to First condition

Ram is 3 years younger than Rohini which means that

x = y -3           .............(i)

Also the other condition is

Their age sum is 37 years

which makes it

x + y = 37    .................(ii)

Now from equation (i) we have the value of x which is

x = y -3

putting this in equation (ii) which is

x + y =37

putting the value

(y-3) + y =37

y - 3 + y =37

2y - 3 = 37

adding three on both sides

2y - 3 +3 = 37 + 3

2y = 40

Dividing both sides by 2

it becomes

y = 20 years

Now in Equation (i)

x = y- 3

Putting the value of y

x = 20 -3

x = 17 years

So their Present ages are Ram 17 years and Rohini 20 years
