Question

the ratio of Neha age to that of Jain is 4:7 and the ratio of Jane's age to that of Smitha is 4:3 .Smitha is 21 years old ,how old is Neha​

Answer 1

hlo mate ✌️

Ratio of age of neha and Jatin = 4/7

Also ,

Ratio of age of Jane and Smitha = 4/3

Age of Smitha = 21 years

According to the condition:

3x = 21

--> x = 7

Age of Jane = 4x = 4 × 7 = 28 years

Again;

According to the condition:

4y/7y

But , 7y =28

y = 4

So the age of Neha = 4 × 4 = 16 years

=> 16 years

Hope it helps ❣️

Answer 2

Neha is 16 years old.

Given,

The ratio of Neha's age to that of Jane is 4:7, and the ratio of Jane's age to that of Smitha is 4:3.

To Find,

Smitha is 21 years old. How old is Neha​?

Solution,

We can solve the question as follows:

Firstly, it is given that the ratio of Neha's age to that of Jane is 4:7.

$Neha's\: age\: : Jane's\: age = 4\: : 7$

It is also given that the ratio of Jane's age to that of Smitha is 4:3.

$Jane's\: age\: : Smitha's\: age = 4\: : 3$

Let the ages of Jane and Smitha be 4x and 3x. It is given that Smitha is 21 years old. Therefore,

$3x = 21$

$x = \frac{21}{3} = 7$

Jane's age = 4x = 4*7 = 28 years.

Now,

Let the ages of Neha and Jane be 4y and 7y.

$7y = 28$

$y = \frac{28}{7} = 4$

Therefore, Neha's age will be:
$Neha's\: age = 4y = 4*4 = 16\: years$

Hence, Neha is 16 years old.
