Numerical Ability
a team p of 20 engineers can complete a task in 32 days.another team q of 16 engineer can complete the same task in 30 days.then ratio of working capacity of 1 member of p to that member of q
Read Solution (Total 4)
-
- P :
20 engineers complete work in 32 days.
20 engineers 1 day work is 1/32.
1 engineer 1 day work is 1/(32*20)
similarly
Q:
16 engineers complete work in 30 days.
26 engineers 1 day work is 1/30.
1 engineer 1 day work is 1/(30*16)
P/Q = (30*16)/(32*20)
= 3/4
so, p:q is 3:4

- Let the capacity of an engineer in P = x units, and in Q = y units.
Working capacity of P = x × 32 × 20
Working capacity of Q = y × 16 × 30
As the total work is same, we equate the above equations.
=> x × 32 × 20 = y × 16 × 30
=> xy = 16 × 30 × 32 × 20 = 34
=>4:3 - 3 years agoHelpfull: Yes(0) No(0)
