The income of A and B are in the ratio 5: 3. The expenses of A, B and C are in the ratio of 8: 5: 2. If C spends 2000 and B saves Rs. 700, then A saves:
Ratio of incomes of A & B are = 5 : 3
Ratio of expenses of A, B & C = 8 : 5 : 2
C’s expenditure = Rs. 2000
∴ B’s expenditure = 5/2 × C’s expenditure
= 5/2 × Rs.2000 = Rs.5000
B’s saving = Rs. 700
B’s income = Expenditure + saving
= Rs. 5000 + Rs. 700
= Rs. 5700
A’s Income = 5/3 of B’s income
= 5/3 × Rs. 5700 = Rs. 9500
A’s Expenditure = 8/2 of C’s expenditure
= 8/2 × Rs. 2000 = Rs. 8000
∴ A’s savings = Rs. 9500 – Rs. 8000
= Rs. 1500
