Question

Why and when fast decouple method is udes?

Answer 1

hey ur method is below

Dear
Here we will use the method of Power = voltage2resistance method .please follow the total solution you will understand the problem  as I trying do it with simple words and simple method to solve this problem .
The rating of the bulb is 200 V -100 W .
So the resistance of the bulb is , R =V2P=(200)2100=400 Ω
Now the bulb burn for 4 hours /day .
So , the energy consumed by the bulb is , E =V2R×t=100×4=400 Wh=4001000=0·4 BOT unit
Now the cost of one unit energy is rupees 4·60  then the cost of energy consumed by the bulb is ,4·60×0·4=1·84 rupees
Regards

Explanation:

Primitive data types are predefined types of data, which are supported by the programming language. For example, integer, character, and string are all primitive data types. ... In the Java programming language, non-primitive data types are simply called "objects" because they are created, rather than predefined.
