Solutions:
1. A) Ratio of prices of potato chips to banana chips sold in 2012 is 4 : 3.
Let’s assume that the respective prices are 4x and 3x.
total revenue in 2012 = (48000 × 4x) + (64000 × 3x) = 384000x
384000x = 1920000
x = 5
Revenue generated by selling banana chips in 2012 = 64000 × 3x = 64000 × 3 × 5 = Rs. 960000
Now, Ratio of prices of potato chips to banana chips sold in 2015 is 1 : 1.
Let’s assume that the respective prices are x and x.
total revenue in 2015 = (96000 × x) + (108000 × x) = 204000x
204000x = 4080000
x = 20
Revenue generated by selling banana chips in 2015 = 108000 × x = 108000 × 20 = Rs. 2160000
Required percentage increase = (2160000 – 960000)/960000 × 100 = 125
2. C) Sale of potato chips in 2016 = 120000
Sale of banana chips in 2016 = 120000
Both the sales go up by 10% in 2017.
sale of potato chips in 2017 = sale of banana chips in 2017 = 120000 + (10% of 120000) = 132000
Now, potato and banana chips are sold at Rs. 23 and Rs. 25 per pack respectively.
Total revenue generated = (132000 × 23) + (132000 × 25) = Rs. 6336000
3. D) Packets of potato chips sold = 72000
Packets of banana chips sold = 70000
Ratio of prices of potato chips to banana chips sold in 2013 is 6 : 5.
Let’s assume that the respective prices are 6x and 5x.
total revenue in 2013 = (72000 × 6x) + (70000 × 5x) = 782000x
782000x = 2346000
x = 3
Revenue generated by selling potato chips = 72000 × 6 × 3 = 1296000
Revenue generated by selling banana chips = 70000 × 5 × 3 = 1050000
Required difference = 1296000 – 1050000 = Rs. 246000
4. A) Aimed revenue by selling potato chips in 2020 = Rs. 6000000
The maximum price of a packet can be Rs. 30.
minimum number of packs to be sold in 2020 = 6000000/30 = 200000
Packs of potato chips sold in 2015 = 96000
Required percentage = (200000 – 96000)/96000 × 100 = 108 1/3
5. B) Average number of potato chips sold per year from 2012 to 2014
= 1/3 × (48000 + 72000 + 80000) = 66666.67
Average number of banana chips sold per year from 2014 to 2016
= 1/3 × (84000 + 108000 + 120000) = 104000
Required difference = 104000 – 66666.67 = 37333.33 ≈ 37333
6. A) Number of bulbs of Ujala manufactured in 2015 = 2500000
Number of bulbs of Ujala termed as defective in 2015 = 5% of 2500000 = 125000
Number of bulbs fit for sale = 2500000 125000 = 2375000
Number of bulbs sold = 80% of 2375000 = 1900000
Total revenue by selling bulbs = 1900000 × 60 = Rs. 114,000,000 = Rs. 114 million
7. C) Number of bulbs of Ujala manufactured in 2013 = 2100000
Number of bulbs of Ujala termed as defective in 2013 = 10% of 2100000 = 210000
Number of bulbs of Ujala fit for sale in 2013 = 2100000 210000 = 1890000
Number of bulbs of Ujala sold in 2013 = 77 7/9% of 1890000 = 1470000
Number of bulbs of Glowmax manufactured in 2013 = 2400000
Number of bulbs of Glowmax termed as defective in 2013 = 12.5% of 2400000 = 300000
Number of bulbs of Glowmax fit for sale in 2013 = 2400000 – 300000 = 2100000
Number of bulbs of Glowmax sold in 2013 = 80% of 2100000 = 1680000
Required ratio = 1470000 : 1680000 = 7 : 8
8. B) Number of bulbs of Ujala manufactured in 2014 = 2250000
Number of bulbs of Ujala termed as defective in 2014 = 11 1/9% of 2250000 = 250000
Number of bulbs of Ujala fit for sale in 2014 = 2250000 250000 = 2000000
Number of bulbs of Ujala sold in 2014 = 90% of 2000000 = 1800000
Number of bulbs of Glowmax manufactured in 2014 = 2500000
Number of bulbs of Glowmax termed as defective in 2014 = 10% of 2500000 = 250000
Number of bulbs of Glowmax fit for sale in 2014 = 2500000 – 250000 = 2250000
Number of bulbs of Glowmax sold in 2014 = 88 8/9% of 2250000 = 2000000
Required difference = 2000000 1800000 = 2,00,000 = 2 lakh
9. D) Number of bulbs of Glowmax manufactured in 2014 = 2500000
Number of bulbs of Glowmax termed as defective in 2014 = 10% of 2500000 = 250000
Number of bulbs of Ujala manufactured in 2012 = 1500000
Number of bulbs of Ujala termed as defective in 2012 = 10% of 1500000 = 150000
Required ratio = 250000 : 150000 = 5 : 3
10. C) Number of bulbs of Glowmax manufactured in 2014 = 2500000
Number of bulbs of Glowmax termed as defective in 2014 = 10% of 2500000 = 250000
Number of bulbs of Glowmax fit for sale in 2014 = 2500000 – 250000 = 2250000
Number of bulbs of Glowmax sold in 2014 = 88 8/9% of 2250000 = 2000000
Number of bulbs of Glowmax manufactured in 2015 = 3000000
Number of bulbs of Glowmax termed as defective in 2015 = 8% of 3000000 = 240000
Number of bulbs of Glowmax fit for sale in 2015 = 3000000 – 240000 = 2760000
Number of bulbs of Glowmax sold in 2015 = 75% of 2760000 = 2070000
Required percentage =2070000−20000002000000×100=3.5=2070000−20000002000000×100=3.5
