1000+ Data Interpretation Aptitude Questions and Answers Pdf - 1

Ans: B

Percentage increase in production of A from 2009 to 2010 = $$[{(700 – 550)} / {550} × 100]$$%

= $$({150}/{550} × 100)$$% = $${300}/{11}$$% = 27.2% = 27%(approx.)

Ans: A

Required % = $$({400}/{550} × 100)$$% = $${800} / {11}$$% = 72.7% = 73% (approx.)

Ans: D

Average production of Company B from 2006 to 2011

= $${1}/{6}$$ × $$[({4}/{5} × 750)$$ + $$({7}/{8} × 800)$$ + $$({4}/{3} × 600)$$ + $$({12}/{11} × 550)$$ + $$({13}/{14} × 700)$$ + $$({14}/{13} × 650)]$$ tones

= $${1}/{6}$$(600 + 700 + 800 + 600 + 650 + 700) tones

= $${4050} / {6}$$ = 675 tonnes.

Ans: D

Total production of Company A = (750 + 800 + 600 + 550 + 700 + 650) tonnes = 4050 tonnes.

Total sales of Company A = (300 + 550 + 450 + 400 + 500 + 550) tonnes = 2750 tonnes.

Required ratio = 4050 : 2750 = $${4050} / {2750}$$ = $${81}/{55}$$ = 81 : 55.

Ans: B

Production of Company B in 2006

= $$({4}/{5} of 750)$$ tones = 600 tonnes.

Production of Company B in 2008

= $$({4}/{3} of 600)$$ tones = 800 tonnes.

Required ratio = 600 : 800 = 3 : 4.
