absent he is paid 3.00/- per day. if he is paid 170/-.how many days he is present.
Read Solution (Total 7)
-
- let no. days be = x and no. days he is absent = 60-x , so 7x - 3(60-x) = 170
x = 35 - 12 years agoHelpfull: Yes(19) No(10)
- The given statement/question seems to be wrong.
let no. days be = x and
hence no. days he is absent = 60-x ,
so as per given statement
7x + 3(60-x) = 170
4x+180= 170
4x= -10
x= -5/2
which is not possible.

- ans is 35 days present... and que has a mistake that if he is absent 1 day den he gave 3 rs as penalty...
thats y 35 days present cost rs 35*7=245 and 25 days absent cost 75 penalty... so
245-75=170....... - 10 years agoHelpfull: Yes(4) No(1)
- 7x-3y=170, x+y=60. on solving, we get x=35, y=25.
- 8 years agoHelpfull: Yes(2) No(0)
- 7x-3y=170
by hit aand trial
7x should be 210
and 3y should be 40.
so no. of working days is 30. - 10 years agoHelpfull: Yes(0) No(2)
- 3*60=180 so its impossible.
