Explanation:

Let's break down the problem:

- Let number of products sold by B in 2015 = x

- Number sold by A in 2015 = 1.5x

- Number sold by A in 2017 = 1.5x + 14

- In 2016, A sold 10% less than 2017 ? 0.9 × (1.5x + 14)

- Ratio of B in 2015 to B in 2017 = 3 : 8 ? B in 2017 = (8/3)x

- B in 2016 = x + 1

- Total for B: x + (x + 1) + (8/3)x = (x + x + 1 + (8/3)x) = (14/3)x + 1

- A and B together in 2017: (1.5x + 14) + (8/3)x = (1.5x + (8/3)x + 14) = ((4.5x+8x)/3 + 14) = (12.5x/3 + 14)

- Total of B = 1 less than total of A and B in 2017

? (14/3)x + 1 = (12.5x/3) + 14 - 1

? (14/3)x + 1 = (12.5x/3) + 13

? (14/3)x - (12.5x/3) = 13 - 1

? (1.5x/3) = 12

? (x/2) = 12

? x = 24

Now,

A in 2017: 1.5x + 14 ? 1.5×24 + 14 = 36 + 14 = 50

A in 2016: 0.9×50 = 45

In 2016, A sold 45 products.

40% in the local market ? 60% transported outside: 0.6×45 = 27

Options:

1. 27

2. 30

3. 35

4. 25

5. None of these

- Statement calculations fit with the found values

- See options, option 1 matches

Correct Answer: Option 1: 27
