Let the total days vivek worked be y.
The days vivek was absent = (30-y)
Now , According to the question
100y - [10 ( 30-y ) ] = 1900
100y - [ 300 - 10y ] = 1900
100y -300 + 10y = 1900
110y = 1900+ 300
110y= 2200
y = 2200/110
y=220/11
y=20
So, Vivek worked 20 days in the month of April and didn't came to work for 10 days .
This will definitely help you dude in one or the other way
Have a awesome and entertaining day!
Keep your head high and go on smiling.
Cheers dude !
