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?

The total expense of a boarding house is partly fixed and partly variable with the number of boarders. When the number of boarders is 25, then the charge is Rs 70 per head and the same is Rs 60 when the number of boarders is 50. What would be the charge per head if there are 100 boarders?

Solution

According to the given condition x + (y/25) = 70 , x + (y/50) = 60
on solving we get y = 500 and x = 50
fixed charge = 50 and remaining 500 rupee of income will be distributed among all the boarders so in last case charge = 50 + (500/100) = 50 + 5 = 55
