Practice Test: Gate Civil Engineering(CE) 2020 Paper: (Session II) - Question 2

The monthly distribution of 9 Watt LED bulbs sold by two firms X and Y from January to June 2018 is shown in the pie-chart and the corresponding table. If the total number of LED bulbs sold by two firms during April-June 2018 is 50000, then the number of LED bulbs sold by the firm Y during April-June 2018 is _________.

Detailed Solution for Practice Test: Gate Civil Engineering(CE) 2020 Paper: (Session II) - Question 2

LED bulbs sold
By  ...(A)

LED bulb sold by Y during April-June
A + B + C = (6 + 8 + 5.5)% = 19.5%
Total LED bulb sold by X and Y 35% this value = 50000
So, LED bulb sold by Y (April to June)

[As 35% of total = 5000

Y (April- June) = 19.5% of total 0.195 × 1442857.14 = 2785.142]
No option is matching.
Mistake in paper was that examiner intended to give total as 50000 and the options were place accordingly as 19.5% of 50000 = 9750 which is (d).
But this will be wrong as total is NOT 50000 as per language. So correct answer is 27857.142.
Which matches with none of options.
