P is 30% of Q, Q is 20% of M, M is 50% of N,what is P/N equal to? [
Read Solution (Total 8)
-
- P = .3Q
Q = .2M
M = .5N
Q = .2M = .2*.5N = .1*N
from 1
P = .3Q = .3*.1*N
=> P/N = .03 - 10 years agoHelpfull: Yes(28) No(1)
- (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. - 10 years agoHelpfull: Yes(2) No(1)
- let n=100
m=50
q=10
p=3
hence p/n=.03 - 10 years agoHelpfull: Yes(2) No(0)
- N M Q P
=N .5N .2*.5N .3*.2*.5N
=>P=.3*.2*.5*N
=>P/N=3*2*5/1000=3/100 - 10 years agoHelpfull: Yes(2) No(0)
- let N=100
M=50
q=10
p=3
so P/N=0.03 - 10 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 - 10 years agoHelpfull: Yes(0) No(0)
