Answer 1

Answer:

The age of Saritha=28 years

The age of Vimala=20 years

Step-by-step explanation:

Given :-

The ages of Sarita and vimla are in the ratio of 7:5. four year later their ages will be in the ratio 4:3.

To find:-

find their ages?

Solution:-

The ratio of the ages of Saritha and Vimala =7:5

Let the present age of Saritha=7x years

The present age of Vimala =5x years

Four years later their ages are 7x+4 and 5x+4 years respectively

Four years later the ratio of their ages=4:3

=>7x+4:5x+4=4:3

=>(7x+4)/(5x+4)=4/3

=>3(7x+4)=4(5x+4)

=>21x+12=20x+16

=>21x-20x=16-12

=>x=4

now ,7x=7×4=28

5x=5×4=20

Answer:-

The age of Saritha=28 years

The age of Vimala=20 years

Answer 2

Step-by-step explanation:

Let, the ages of sarita and vimla be 7x and 5x.

A/Q,

7x+4/5x+4 = 4/3.

=>3(7x+4) = 4(5x+4).

=>21x+12 = 20x+8.

=>21x-20x = 8-12.

=> x = -4.

Therefore,

The ages of sarita and vimla is 7(-4) = -28.

5(-4) = -20.
