Question

1. A father is 6 time as his son after your years he will be only four time as old as his son will be what are there present age?
2. Shreyansh things of number and add 7 by 2 to it. multiply the result by 5. The result now obtained is 4 time the same number he thought of what is the number?

Answer 1

Answer:

Let the father’s age be y;

Let the son’s age be x;

So from the first condition: [math]y = 6x[/math]

After 6 years, the father’s and son’s age will be : y+6 & x+6 years respectively.

Therefore, from the second condition: [math]y+6 = 3 (x+6)[/math]

Substituting y as 6x in above equation we get,

6x+6 = 3x+18 ……………………………. on opening the brackets

3x = 12 or x = 4

Therefore, y = 6x = 6 x 4 = 24

Hence, the father’s age is 24 years and son’s age is 4 years.

Hope you understood!

Step-by-step explanation:

let the number be x

x+7/2=2x+7/2

now,

5(2x+7/2) = 10x+35/2

now,

4x= 10x+35/2

4x×2= 10x+35

8x=10x+35

-35=10x-8x

-35=2x

-35/2=x= -17.5
