NOTE: This question is similar to one of the OG questions
ANSWER:C
Each type P machine can assemble 240 cars per hour, each type Q machine can assemble 360 cars per hour, and each type R machine can paint 1500 cars per hour. Any car is painted only when it is completed assembled. Find out, for a particular hour, what is the total number of machines working?

(1) A total of 6,000 cars are assembled and painted every hour.
P = no. of P type machine
Q = no. of Q type machines

240*P + 360*Q =6000
R= 1500 cars per hours
number of R machines = 4
=> No idea about P and Q, it can be (10,10) OR (19,4)
INSUFFICIENT


(2) For that one hour, there are 5 Type Q machines working for every 2 Type R machine working.­
   Q/R = 5/2
it gives only ratio hence, INSUFFICIENT

COMBINING 1 and 2
240*P + 360*5*R/2 = 6000
R=4
P =10
Q =10
SUFFICIENT­
