Question

reenas mother age is 4 times her age after 5 years her mother will be 3 times her age find her present age

Answer 1

Her present age is 10 years and her mother age is 40 but after five year her age will 15 and her mother age will 45

Answer 2

Let the present age of mother be x
and Reena be y

x = 4 y ..... ( i )

After 5 years,

( x + 5 ) = 3 ( y + 5 )

x + 5 = 3y + 15

x - 3y + 5 - 15 = 0

x - 3y - 10 = 0 ..... ( ii )

Putting the value of x from i in ii

x - 3y - 10 = 0

4y - 3y = 10

y = 10

Putting the value of y in ( i )

x = 4y

x = 4 × 10

x = 40


The present age of Mother is 40years
and the present age of Reena is 10
