Question

Present ages of anu and raj are in the ratio 4 is to 5 eight years from now the ratio of their ages will be 5 is to 6.Find their present ages

Answer 1

Step-by-step explanation:

(4x+8)/(5x+8)=5/6

cross multiplying we get

6(4x+8)=5(5x+8)

=24x+48=25x+40

=48-40=25x-24x

=x=8

Present age4x=4×8=32

5x=5×8=40

Answer 2

Step-by-step explanation:

Let the ratios be x.

So,

The ratio of their present ages :

4x : 5x

Their ages after 5 years :

4x + 8/5x + 8

Their ratio after 5 years :

5 : 6

We got equation :

4x + 8/5x + 8= 5/6

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

Solution :

= 4x + 8/5x + 8 = 5/6

= (4x + 8)6 = 5(5x + 8)

= 24x + 48 = 25x + 40

= 24x - 25x = -48 + 40

= -x = -8

= x = 8

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

Age of Anu (4x) = 32 years.

Age of Raj (5x) = 40 years
