If 20 oranges cost Rs 150, find the price of 16 oranges

Answer

To find the price of 16 oranges when 20 oranges cost Rs 150, we can follow these steps:

### Step 1: Find the cost of one orange.
To find the cost of one orange, we divide the total cost of 20 oranges by the number of oranges.

\[ \text{Cost of one orange} = \frac{\text{Total cost of 20 oranges}}{\text{Number of oranges}} = \frac{150}{20} \]

### Step 2: Simplify the fraction.
Now, simplify the fraction:

\[ \frac{150}{20} = \frac{150 \div 10}{20 \div 10} = \frac{15}{2} \text{ Rs} \]

### Step 3: Calculate the cost of 16 oranges.
Now that we know the cost of one orange, we can find the cost of 16 oranges by multiplying the cost of one orange by 16.

\[ \text{Cost of 16 oranges} = 16 \times \frac{15}{2} \]

### Step 4: Simplify the multiplication.
To simplify this calculation, we can multiply 16 by 15 and then divide by 2:

\[ 16 \times \frac{15}{2} = \frac{16 \times 15}{2} \]

Now, divide 16 by 2:

\[ \frac{16}{2} = 8 \]

So, we have:

\[ 8 \times 15 = 120 \text{ Rs} \]

### Final Answer:
The cost of 16 oranges is Rs 120.
