Number of workers and time taken to complete the specified work, 5. Circumference of the circle to its radius

Answer 1

1.Price of pulses to their consumption - Inverse proportion (as the price increases, consumption tends to decrease, and vice versa)

2. Weight of rice to their cost - Direct proportion (as the weight increases, the cost also increases proportionally)

3. Speed of the car and time taken to cover a certain distance - Inverse proportion (as the speed increases, the time taken decreases, and vice versa)

4. Number of workers and time taken to complete the specified work - Inverse proportion (as the number of workers increases, the time taken decreases, and vice versa)
