Richa is in gadget for 20 days on the condition that she will receive rupees 60 for each desi work and will be fine rupees 5 for HTC is absent if C receive rupees 7:45 in all how many days did you remain absent?​

Next time please try to put clear images

Let he worked for x days and absent for (20-x) days.

So, according to question, he gets 60 rs for each working day and -5 for each absent days.

SO for working days he earns 60x and for absent he gave fines of (20-x)* (-5),

So, the equation will be

60x+ (20-x)*(-5)=745

60x-100+5x=745

65x-100=745

65x=845

x=845/65=13.

So, He worked only for 13 days, Now we need to calculate the number of days he was absent, so it will be 20–13=7 days.

The answer will be 7 days.
