Question

P,q,r,s and t are five positive numbers satisfying p=3q=4r and 2q=5s=12t.which of the following pairs contain a number that can never be an integer

Answer 1

Answer:

Let us assume:

P=3Q=4R= 60K .........(A bigger common multiple for easy calculation)

P=60K

Q=20K

R=15K

Now Given:2Q=5S=12T...........(Substituting the value of Q)

Therefore

S=8K

T=(10/3)K

S/R=(8/15)

Hence answer is D.
