b$)$ A step$-$drawdown pumping test was conducted in a groundwater basin containing a confined aquifer. The pumping rate of a step along with the drawdown observed in the observation well located $50m$ away from the pumping well of radius $10cm$ and $500m$

radius of influence are given in the following table. Using the given data, find i$)$ Well condition, ii$)$ Well efficiency, iii$)$ Transmissivity, and v$)$ Storage coefficient
