Answer

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the total amount of petrol filled.
The taxi driver filled:
- 40 liters of petrol on Monday
- 50 liters of petrol on Tuesday

**Total petrol filled = 40 liters + 50 liters**

**Total petrol filled = 90 liters**

### Step 2: Calculate the cost of petrol per liter.
The cost of petrol is given as Rs. 44 per liter.

### Step 3: Calculate the total cost of petrol.
To find the total cost, we multiply the total liters of petrol by the cost per liter.

**Total cost = Total petrol filled × Cost per liter**

**Total cost = 90 liters × Rs. 44/liter**

### Step 4: Perform the multiplication.
Now, we calculate:

- 90 × 44 = 3960

### Final Answer:
The total amount spent by the taxi driver on petrol is Rs. 3960.
