Question

Sum of the ages of two brothers is 36years and the difference between their ages is 10years.

Find their age​

Answer 1

Answer:

The. Answer is 24 .

Let's see how we calculated this mathematical question.

We have given the sum of there current age= 36

The ratio of there age after 4 years is also given=5:6

Now let's get started

Age of younger brother after 4 years=5x

Age of older brother after 4 years= 6x

(Note: Taken by the given ratio.)

Now,

There current age =(There age after 4 years- 4)      

Current age of younger brother =(5–4=1x)

Current age of older brother=(6–4=2x)

Now we have given that the sum of there current age is 36

So, we will equate this as follows

1x+2x= 36

3x=36

x=12

Age of elder brother = 2x= 2*12=24

Answer 2

Step-by-step explanation:

x+y=36

x-y=10

2x=46

x=23

we will substitute x with its value

x+y=36

y=36-23

y=13
