(A) 18
(B) 27
(C) 36
(D) 48
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.)

(A) 73%

(A) 574
(B) 593
(C) 649
(D) 675
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.
Question: 4

(A) 64 : 55
(B) 71 : 55
(C) 71 : 81
(D) 81 : 55
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.
Question: 5
What is the ratio of production of Company B in the year 2006 to production of Company B in the year 2008?
(A) 2 : 5
(B) 3 : 4
(C) 3 : 5
(D) 3 : 6
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.
