Question

The Ratio of Rita's age to her mother's age is 2:5. If her mother is 45 years old how old is Rita?​

Answer 1

${{\bold{\underline{\overline{\overline{★Let \: their \: ages:-}}}}}}$

Let at present time age of Abha = x

at time of birth age of Abha = 0

at time of birth age of her mother = 27

${{\bold{\underline{\overline{\overline{★According \: to \: question:-}}}}}}$

when Abha will become x year's old her mother will become X+27

Thus X/X+27= 2/5

${{\bold{\underline{\overline{\overline{★Solution:-}}}}}}$

5X−2X=5M

X=18

Abha's age = 18 yrs

Mother's age = 18+27= 45 yrs.

Answer 2

Answer:

Rita is 18 year

Step-by-step explanation:

According to the information provided in the question it is given as

Ratio Rita age to mother age =2:5

Mother age =45

We need to find the age of Rita

Here we first make an equation to solve the problem

Let the age of Rita is =x

Rita : Mother

2:5

x: 45

Hence by simple cross multiplication we get the value of x

$5x =45\times 2\\5x=90\\x=\frac{90}{5}$

Converting to lowest term

$x = 18$

Hence the age of Rita is 18 year
