Question

Anu is 20 years older than rinu. she is also 6 times as old as rinu. find their ages

Answer 1

Anu is 24 years old and Rinu is 4 years old.

Step-by-step explanation:

To solve this problem, we can set up a system of equations to represent the information given. Let's use 'A' to represent Anu's age and 'R' to represent Rinu's age. From the information given, we can write two equations:

1. A = R + 20 (Anu is 20 years older than Rinu)

2. A = 6R (Anu is 6 times as old as Rinu)

We can solve this system of equations using substitution or elimination method.

Substituting the value of A from the second equation into the first equation, we get:
R + 20 = 6R
20 = 6R - R
20 = 5R
R = 4

Now, substituting the value of R into the first equation, we can find Anu's age:
A = R + 20
A = 4 + 20
A = 24

Therefore, Anu is 24 years old and Rinu is 4 years old.

Answer 2

Step-by-step explanation:

let Rinus age be R

Anu's age is equal to 20+R and 6×R

20+R=6×R

20+R=6R

Collect like terms

20=6R-R

5R=20

Divide both sides by 5

R=20/5

R=4

Therefor Rinu is 4 years while Anu is 20+4 which is 24 years
