Question:-

The age of Remya and the double the age of Sophie added together gives 28. Three fourth of Remya age adeed to one forth of Sophie age gives 11. Find the age of Sophie and Remya ?

Given:-

  • The age of Remya and the double the age of Sophie added together gives 28.
  • Three fourth of Remya age adeed to one forth of Sophie age gives 11.

Solution:-

Let, 'x' be the age of Remya and 'y' be the age of Sophie.

{ According to given }

—› x + 2y = 28 ...... ( 1 )

—› (3/4)x + (1/4)y = 11 ...... ( 2 )

{To find age of Remya}

Multiply the eq. ( 2 ) by 8, we get

—› 6x + 2y = 88 ....... ( 3 )

Now, subtract eq. ( 3 ) from eq. ( 1 )

x + 2y = 28

- ( 6x + 2y = 88 )

_________________

- 5x = - 60

5x = 60

x = 60/5

x = 12

{To find age of Sophie}

Put value of x in eq. ( 1 )

—› x + 2y = 28

—› 12 + 2y = 28

—› 2y = 28 - 12

—› 2y = 16

—› y = 16/2

—› y = 8

{According to assumption}

Hence the age of Remya is 12 years and age of Sophie is 8 years.
