Vedclass · Answer

(A) Given, the ratio of incomes of $A, B, C$ is $3: 7: 4$.Income of $A = Rs. 2400$.Since $3$ units $= 2400$, $1$ unit $= 800$.Income of $B = 7 	imes 800 = Rs. 5600$.Income of $C = 4 	imes 800 = Rs. 3200$.Expenditure of $A = 	ext{Income} - 	ext{Saving} = 2400 - 300 = Rs. 2100$.The ratio of expenditures is $4: 3: 5$.Since $4$ units $= 2100$, $1$ unit $= 525$.Expenditure of $B = 3 	imes 525 = Rs. 1575$.Expenditure of $C = 5 	imes 525 = Rs. 2625$.Saving of $B = 	ext{Income of } B - 	ext{Expenditure of } B = 5600 - 1575 = Rs. 4025$.Saving of $C = 	ext{Income of } C - 	ext{Expenditure of } C = 3200 - 2625 = Rs. 575$.

The ratio of the incomes of $A, B$ and $C$ is $3: 7: 4$ and the ratio of their expenditures is $4: 3: 5$. If in the income of $Rs. 2400$, $A$ saves $Rs. 300$, then the savings of $B$ and $C$ respectively are:
