A finishes a work in 10 days, B finishes a work in 15 days.
They worked together. 5000 has to be shared b/w A & B. How much does A get??
Ans : 3000
Read Solution (Total 6)
-
- 1/10+1/15=1/6
6 day to complete work
work rate*time = work done
A's work done is =1/10*6
now A's share=6/10*5000
=>3000 Ans. - 10 years agoHelpfull: Yes(33) No(0)
- their work ratio would be 3:2
now A's share would be 3/5*5000=3000 - 10 years agoHelpfull: Yes(12) No(3)
- A work for 10 days
B work for 15 days
L.c.m of 10 and 15 is 30
A's share is L.c.m/10=30/10=3
B's share is L.c.m/15=30/15=2
A and B's share is 3:2
3x+2x=5000
5x=5000
x=1000
then A's share is 3x=3*1000=3000

- By alligation method work ratio is 3:2
so,A=(3/5)*5000=3000
- 10 years agoHelpfull: Yes(1) No(0)
- A work in 10D
B work in 15D
total work is lcm of 10 & 15=30
A's on day work 3
B's one day work is 2
per day a work 3 parts & b work 2 parts
3 parts of 5000 is 3000,
hence A get 3000 - 10 years agoHelpfull: Yes(0) No(0)
- one day work of A=1/10
one day work of B=1/15
l.c.m of 10 and 15=30
therefore A=3
B=2
A's share=3/5*5000
=3000 - 10 years agoHelpfull: Yes(0) No(0)
