The ratio of incomes of C and D is 3 : 4 and their expenditures is 4 : 5. If the savings of C is one fourth of his income then what is the ratio of savings of C and D?

Solution

According to the given condition
3x - 4y = (1/4)3x
=> (3/4)3x = 4y
=> 9x = 16y
=> x/y = 16/9
so ratio of savings = (3x - 4y)/(4x - 5y) = (3*16 - 4*9)/(4*16 - 5*9) = 12/19
