Question

reena is 4 years older than her sister meena. if the sum of their ages is 36 years. what are the age of reena and meena.​

Answer 1

Answer:

Age of Meena = 16 years

Age of Reena = 20 years

Step-by-step explanation:

Let age of Meena = x years

According to question- Reena is 4 years older than Meena

So, age of Reena = (x + 4) years

Given that, the sum of their ages is 36.

x + (x + 4) = 36

2x + 4 = 36

2x = 36 - 4

2x = 32

$x = \dfrac{32}{2}$

x = 16

So, age of Meena = x

Age of Meena = 16 years

Age of Reena = x + 4

                       = 16 + 4

Age of Reena = 20 years

Answer 2

Answer: Reena is 20 and Meena is 16

Step-by-step explanation:

Reena is 4 years older than Meena so, if Reena is 5 years old, Meena must be 1 year old.

The sum of the ages of Reena and Meena is 36

36 can be represented as 18+18,

the difference between Reena and Meena is 4,

Lets us minus 2 from second 18 and add it to the 1st 18 i.e 20+16=36.

so Reena must be 20 and her sister Meena must be 16.
