Solution

Let's solve this step by step:

Step 1: Let's assume the income of P and Q as 3x and 5x respectively. Similarly, let's assume their expenditures as y and 2y respectively.

Step 2: According to the problem, P saves Rs. 1200. So, we can write the equation for P as: Income - Expenditure = Savings 3x - y = 1200 ---- (Equation 1)

Step 3: Similarly, Q saves Rs. 800. So, we can write the equation for Q as: Income - Expenditure = Savings 5x - 2y = 800 ---- (Equation 2)

Step 4: Now, we have two equations and we can solve them simultaneously. Multiply Equation 1 by 2, we get: 6x - 2y = 2400 ---- (Equation 3)

Step 5: Now, subtract Equation 2 from Equation 3, we get: x = 1600

Step 6: Substitute x = 1600 in Equation 1, we get: 3*1600 - y = 1200 4800 - y = 1200 y = 4800 - 1200 y = 3600

So, the income of P is 3x = 3*1600 = Rs.4800.

So, the correct answer is Rs.4800.
