Question

The ratio between the ages of Mamatha & Samatha is 4:3. What will be the sum of their ages after 3 years​

Answer 1

Answer:

-----------

Ratio of ages of Namrata and Divya = 4:3

Sum of their ages = 28 years

SOLUTION

-----------------

TO FIND THEIR PRESENT AGES :

------------------------------------------------

Let the ages be 4x and 3x

=> 4x + 3x = 28

=> 7x = 28

=> x = 28/7

=> x = 4

Age of Namrata = 4 × 4 = 16 years

Age of Divya = 3 × 4 = 12 years

THEIR AGES AFTER 4 YEARS :

---------------------------------------------

Age of Namrata = 16 + 4 = 20 years

Age of Divya = 12 + 4 = 16 years

Answer 2

Answer:

$\huge\rm{Given \: that,}$

Ratio of Ages of Mamatha and Samatha = 4:3

Total sum of their ages = 3 years

$\rm{To \: find:-}$

Their present ages

$\rm{Let \: the \: ages \: be:-}$

4x and 3x

$\huge\rm{Solution,}$

= 4x + 3x = 3

= 7x = 3

= x = 3/7

x = 3/7

Age of Mamatha = 4 × 3/7 = 12/7 years

Age of Samatha = 3 × 3/7 = 9/7 years

$\rm{Age \: after \: 3 \: years:-}$

Age of Mamatha = 12/7 + 21/7 = 33/7

Age of Samatha = 9/7 + 21/7 = 30/7
