Question

The income of x,y and z are in the ratio 2:3:5 respectively. if the income of y is rs 9000, then by what is income of z more than that of x ?

Answer 1

9000 because if we take the ratios as 2a 3a and 5a ...so 3a=9000 so a=3000 So the icome of z is 15000 (5a) and income of x is 6000 so z is 9000 more than. that of x

Answer 2

let the ratio be 2k:3k:5k
given that 3k= 9000
k => 9000/3
k => 3000
income of x= 2k
i.e., 2×3000
= 6000 Rs.
income of z= 5k
i.e., 5×3000
= 15000 Rs.
difference between z and x is
= 15000-6000
= 9000 Rs
z is 9000 Rs much more than x....
