bottles manufactured by companies P, Q and R in
2017 were defective and none of the glass bottles
were defective, then what was the total number of
defective bottles manufactured by the 3 companies

of these

by companies P, Q and R was 9000, 7500 and 8000 respectively. What was the ratio of the total
number of plastic bottles manufactured by Q to the total number of plastic bottles manufactured
by P and R combined?
a) 15 : 19 b) 3:19 c) 24:17 d) 15:13 e) None of these
3) The total number of bottles manufactured by company Q in 2015 and 2016 was 6000 and 10000
