Question

Ram is 3 times as old as rahim five year later, ram will be. Two and half times as old as rahkm . How old are ram and rahim now

Answer 1

Hey

Here is your answer,

Let the present age of Ram be x and Rahim be y.

Then, x = 3y
Given, x + 5 = 2½times (y+5)

Putting the value of x in the second equation,
we get,
3y + 5 = 5/2 × (y + 5)
3y + 5 = 5/2 + 25/2
3y - 5/2 = 25/2 - 5
1/2y = 15/2
SO, y = 15/2 × 2
y = 15

Putting this value in the first equation,
we get,
x = 3y
x = 3 × 15
x = 45.

Hence, age of Ram is 45 and Rahim is 15

Hope it helps you!

Answer 2

let rahim's age be x
3x+5/x+5= 5/2
3x+5=5/2(x+5)
x+5=5x/2+25/2
= 6x+6=25+5x
x=25-6
= 19
