To complete a work P takes 50% more time than Q.If together they take 18 days to complete the work,how much time shall Q take to do it
a.30 days
b.35 days
c.40 days
d.45 days
Read Solution (Total 2)
-
- lets Q takes X days to complete a work,so P takes (X+X/2) means 3X/2 days.
so 1 day P work is=2/3X
and 1 day Q work is=1/X
so bath of together do 1 day =1/X+2/3X work
and according to question 1/X+2/3X=1/18
to solve this equation the value of x=30
so ans is 30. - 10 years agoHelpfull: Yes(1) No(1)
- 150 A = 100 B
3 A = 2 B
A = 2/3 B
A+B = 1/18
2/3 B + B = 1/18
5/3 B = 1/18
B = 3/90 = 30 DAYS - 8 years agoHelpfull: Yes(0) No(0)
