P is 30% of Q, Q is 20% of M, M is 50% of N,what is P/N equal to? [

• P = .3Q
  Q = .2M
  M = .5N
  
  Q = .2M = .2*.5N = .1*N
  from 1
  P = .3Q = .3*.1*N
  => P/N = .03

• (P/Q)*(Q/M)*(M/N)=(30/100)*(20/100)*(50/100)=(3/100)=3%

• ans is 3/100.
  P=30/100*Q .............(1)
  and Q=20/100*M
  put the value of Q in eq 1
  P=6/100*M ........(2)
  and M=50/100*N
  put value of M in eq (2)
  the P=3/100*N
  so the ratio of P/N=3/100.

• let n=100
  m=50
  q=10
  p=3
  hence p/n=.03

• N M Q P
  =N .5N .2*.5N .3*.2*.5N
  =>P=.3*.2*.5*N
  =>P/N=3*2*5/1000=3/100

• let N=100
  M=50
  q=10
  p=3
  so P/N=0.03
• 9 years agoHelpfull: Yes(1) No(0)
• P=30%*Q
  Q=20%*M
  M=50%*N
  therefore P=30%Q
  =30%*20%*M
  P=30%*20%*50%*N
  BY SOLVING THIS, WE GET;
  P=3N/100
  P/N=0.03

• let us assume N=800;
  Then M=800*50/100=400;
  Q=400*20/100=80;
  P=80*30/100=24;
  Hence P/Q=24/800=3/100 or .03
