`(3)/(5)` quital of wheat cost Rs. 210. find the cost of :
1 quintal of wheat

Answer

To find the cost of 1 quintal of wheat when \( \frac{3}{5} \) quintal costs Rs. 210, we can follow these steps:

### Step 1: Understand the given information
We know that \( \frac{3}{5} \) quintal of wheat costs Rs. 210.

### Step 2: Set up the equation
Let the cost of 1 quintal of wheat be \( x \). We can express the relationship as:
\[ \frac{3}{5} \text{ quintal} = 210 \text{ Rs} \]

### Step 3: Find the cost of 1 quintal
To find the cost of 1 quintal, we can set up a proportion:
\[ \frac{3}{5} \text{ quintal} = 210 \text{ Rs} \implies 1 \text{ quintal} = x \text{ Rs} \]
To find \( x \), we can multiply both sides of the equation by \( \frac{5}{3} \):
\[ x = 210 \times \frac{5}{3} \]

### Step 4: Calculate the cost
Now, we perform the calculation:
\[ x = 210 \times \frac{5}{3} = 210 \times \frac{5}{3} = 210 \times 1.6667 \approx 350 \]

### Step 5: Conclusion
Thus, the cost of 1 quintal of wheat is Rs. 350.
