Question Numbers (1 to 5): An air conditioner (AC) company has four dealers – D1, D2, D3 and D4 in a city. It is evaluating sales performances of these dealers. The company sells two variants of ACs – Window and Split. Both these variants can be either Inverter type or Noninverter type. It is known that of the total number of ACs sold in the city, 25% were of Window variant, while the rest were of Split variant. Among the Inverter ACs sold, 20% were of Window variant.

The following information is also known:
1. Every dealer sold at least two window ACs.
2. D1 sold 13 inverter ACs, while D3 sold 5 Non-inverter ACs.
3. A total of six Window Non-inverter ACs and 36 Split Inverter ACs were sold in the city.
4. The number of Split ACs sold by D1 was twice the number of Window ACs sold by it.
5. D3 and D4 sold an equal number of Window ACs and this number was one-third of the number of similar ACs sold by D2.
6. D2 and D3 were the only ones who sold Window Non-inverter ACs. The number of these ACs sold by D2 was twice the number of these ACs sold by D3.
7. D3 and D4 sold an equal number of Split Inverter ACs. This number was half the number of similar ACs sold by D2.

Q. 1 How many Split Inverter ACs did D2 sell?

14

Explanation

Total number of Split Inverter ACs sold by D2 = 14

Q. 2 What percentage of ACs sold were of Non-inverter type?

2

Explanation

Total number of ACs sold = 60; Total number of Non-inverter ACs sold = 15
Hence, required percentage = 15/60 x 100 = 25%.

Q. 3 What was the total number of ACs sold by D2 and D4?

33

Explanation

Total number of ACs sold by D2 and D4 = 60 – (15 + 12) = 33.

Q. 4 Which of the following statements is necessarily false?

1

Explanation

D1 and D3 together sold 27 ACs whereas D2 and D4 sold 33 ACs. Hence, option (1) is necessarily false.
All the other statements are not necessarily false.
Hence, the correct answer is option (1).

Q. 5 If D3 and D4 sold an equal number of ACs, then what was the number of Non-inverter ACs sold by D2?

1

Explanation

If D3 and D4 sold equal number of ACs, then the total number of ACs sold by D2 = 60 – (15 + 12 + 12) = 21.
Total number of Non-inverter ACs sold by D2 = 21 – 16 = 5.
