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

• 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

• Sorry guys its 16 not 26 in Q.

• 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
