The incomes of A and B are in the ratio 5 : 3. The expenditure of A, B and C are in the ratio 8 : 5 : 2. If C spends ₹2000 and B saves ₹700, then what amount does A save ?
Answer & explanation
Correct answer: option 1
Income, A : B = 5:3
Expenditure, A : B : C = 8:5:2
C spends = 2000
B:C = 5:2
B:2000 = 5:2
B Expenditure = 5*2000/2 = 5000
B saves = 700
B's income = 5000+700 = 5700
Expenditure, A:B = 8:5
Exp A:5000 = 8:5
Exp A = 5000*8/5 = 8000
Income A:B = 5:3
Income A : 5700 = 5:3
Income of A = 5700*5/3 = 9500
Savings of A = 9500-8000 = 1500
The correct answer is option (1) : ₹1500
