What is the ratio of the average production of Company X in the period 1998-2000 to the average production of Company Y in the same period?
1:1
15:17
23:25
27:29
Correct answer is C
Average production of Company X in the period 1998-2000
= [ 1/3 x (25 + 50 + 40) ] = ( 115/3 ) lakh tons
Average production of Company Y in the period 1998-2000
= [ 1/3 x (35 + 40 + 50) ] = ( 125/3 ) lakh tons
Therefore Required ratio = (115/3)/(125/3) = 115/125 = 23/25
