let their monthly income be 3x and 4x and their expenditures are 4a and 5a.

from the given information income of C is 1/4 of his income i.e.3x/4.

we know that

income-expenditure savings

so in that case savings of C 3x-4a

so 3x-4a 3x/4

x 16a/9

therefore savings of c 4a/3 and that of D 19a/9

ratio of their savings 12:19

Let the income of C&D be

C 3x

D 4x

Let the expenditure of C&D be

C 4a

D 5a

Savings income-expediture

Savings of C 3x-4a

Savings of D 4x-5a

Given 3x-4a 1/4(3x)

x 16a/9

Therefore savings of C 3(16a/9)-4a

12a/9

Savings of D 4(16a/9)-5a

19a/9

Ratio (12a/9):(19a/9) 12:19

Ratio of savings of C & D are 12:19
