Answer:
let the earlier rate of elec. be x
and no. of consumers be y
so total revenue =x×y
then rate increased by 5% so new rate = 1.05x
and consumers decreased by 8%
new no of consumers = .92%
so new revenue =1.05x ×.92y=.966xy
so change in revenue =.966xy-xy=-.034xy
here negative sign represent decrease
now given total decrease =680000
so .034xy=680000
so xy=680000/.034
xy=2,00,00,000
this is the original revenue.
