Question

Solve this problem....

Answer 1

Hello friends

___________________________

Let ,

a = 7k ,b = 3k

==> a + 2b/a - 2b = 7k + 2 x 3k/7k -2 x 3k


==> 7k + 6k/7k - 6k


==> 13k/k

==> 13/1


hence,

a + 2b/a - 2b = 13/1


I hope this will help you...

Thanks...

:)

Answer 2

a/b=7/3
i.e. a=7 &b=3
The ratio is,a+2b/a-2b
Now put the value of a&b in given ratio
7+2(3)=13 [a+2b]
7-2(3)=1 [a-2b]
So the ratio is 13/1...
