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.
