Test Preparation on Mathematics Olympiad Class-7 Test Prep-1
1.
Weight of P is twice that of
Q. Weight of Q is half of
R. Weight of R is 3 times of
T. Weight of T is half of
S. The weight of
Q is greater than the weight of how many persons among P, R, S, and T?
P=2Q
Q=R/2 => Q/R=2/1
R=3T =>2Q=3T => Q/T=3/2
T=S/2 =>S/2=2Q/3 => Q/S=4/3
So weight of ‘Q’ greater than ‘S’.
