Question

1 ) Age of Remya and double the age of Sofi added together gives 28 . Three– fourth of
Remya's age added to one-fourth of Sofi's age gives 11 . Find the age of Remya and age of Sofi ?

Answer 1

Answer:

Ramya age = 12

sofi's age. = 8

Step-by-step explanation:

let Ramya age = x

Sofi's age. = y

according to above two statements,

x + 2y = 28.

and. 3/4 (x) + 1/4 (y) = 11

L.C.M of coefficient of both y = 8

8 | x (3/4) + y (1/4) = 11 |

= 6x + 2y = 88

Now,

$(x + 2y = 28) - (6x + 2y = 88)$

= -5x = -60

x = 12

Then,

y = (28-x)/2

= 8
