Question

The monthly income if A is Rs. 12000 more than that of B. The Monthly savings of B is Rs 4000 less than that of A. The Ratio of monthly expenditure of A and B is 4:3. Find expenditure of A

Answer 1

Answer:

32000

Step-by-step explanation:

Let the monthly income of A = X

Therefore monthly income of B = X-12000

Let the monthly savings of A = Y

Monthly savings of B = Y-4000

Monthly expenditure of A = X-Y

Monthly expenditure of B = (X-12000)-(Y-4000)

ATQ, (X-Y)/(X-12000-Y+4000) = 4/3

Hence, 3(X-Y) = 4(X-Y-8000)

X-32000 = Y

X-Y = 32000

Therefore Monthly Expenditure of A = 320000
