Sol: Let the no. of extra units = x
   Thus,

 {tex}\text {Let the original bill = y Rs.}\\ \text {Therefore, Original amount+ 20% fine = 28363.20}\\ \text {=> y + 20% of y = 28363.20}\\ \text {=> y + }{\frac{20}{100}}\times \text{ y = 28363.20}\\ \text {=> }{\frac{120}{100}}\times \text{ y = 28363.20}\\ \text {=> }{\frac{6}{5}}\times \text{ y = 28363.20}\\ \text {=> }\text{ y = }{28363.20\times {\frac{6}{5}}}\\ \text {=> y = }\boxed{23636 Rs.}\\ Now, {=> \ 1910 + 71\times x = 23636}\\ {=> \ 71\times x = 23636-1910}\\ {=> \ 71\times x = 21726}\\ {=> \ x = \frac{21726}{71}}\\ {=> \ x = \boxed{306}}\\{/tex}

So, the Former reading of the meter was = 4777 - 306 = {tex}\huge {\boxed{4471} \ units.} \\ All \ the\ best\ :-)...{/tex}
