An electricity board charges the following rates for the use of electricity: for the first 200 units 80 paise per unit: for the next 100 units 90 paise per unit: beyond 300 units Rs 1 per unit. All users are charged a minimum of Rs. 100 as meter charge. If the total amount is more than Rs 400, then an additional surcharge of 15% of total amount is charged. Write a program to read the name of the user, number of units consumed and print out the charges. Program and Algorithm Computer Science Engineering VTU

Start

Read name, units consumed as units

charge = 100

if units is <= 100 then 

compute charge = charge + units * 0.8 

else If units > 200 and units < 300 then 

compute charge = charge + 200 * 0.8 +(units – 200) * 0.9 

else 

compute charge = charge + (0.15*charge) 

Display name, units, charge
