Question

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?

• A. 1 : 1
• B. 15 : 17
• C. 23 : 25
• D. 27 : 29

Answer 1

The correct option is C 23 : 25

Average production of Company X in the period 1998-2000
$=[\frac{1}{3}\times (25+50+40\left)\right]=\left(\frac{115}{3}\right)$ lakh tons.
Average production of Company Y in the period 1998-2000
$=[\frac{1}{3}\times (35+40+50\left)\right]=\left(\frac{125}{3}\right)$ lakh tons.
$\therefore$ Required ratio $=\frac{\left(\frac{115}{3}\right)}{\left(\frac{125}{3}\right)}=\frac{115}{125}=\frac{23}{25}$
