The table below shows the cost price (in Rupees) and sale price (in Rupees) of four items for five years.
Year Item A Item B Item C Item D Cost Price Sale price Cost Price Sale Price Cost price Sale Price Cost Price Sale Price 2015 200000 230000 100000 110000 25000 28750 25000 28750 2016 140000 161000 150000 165000 27500 31625 27500 31900 2017 210000 241500 160000 176000 40000 44000 30000 35100 2018 185000 212750 190000 209000 33300 38295 40000 47200 2019 170000 195500 199500 221445 34000 39100 34000 40460
To determine which item maintains the same percentage profit on cost every year, we need to calculate the percentage profit for each item across all years provided and check for consistency. The formula to calculate the percentage profit is:
\text{Percentage Profit} = \left( \frac{\text{Sale Price} - \text{Cost Price}}{\text{Cost Price}} \right) \times 100 \%
Let's calculate the percentage profit for each item from 2015 to 2019:
Item A:
- 2015: \frac{230000 - 200000}{200000} \times 100 = 15\%
- 2016: \frac{161000 - 140000}{140000} \times 100 = 15\%
- 2017: \frac{241500 - 210000}{210000} \times 100 = 15\%
- 2018: \frac{212750 - 185000}{185000} \times 100 = 15\%
- 2019: \frac{195500 - 170000}{170000} \times 100 = 15\%
Item A maintains a constant 15% profit every year.
Item B:
- 2015: \frac{110000 - 100000}{100000} \times 100 = 10\%
- 2016: \frac{165000 - 150000}{150000} \times 100 = 10\%
- 2017: \frac{176000 - 160000}{160000} \times 100 = 10\%
- 2018: \frac{209000 - 190000}{190000} \times 100 = 10\%
- 2019: \frac{221445 - 199500}{199500} \times 100 \approx 10.99\%
Item B does not maintain a constant profit percentage each year.
Item C:
- 2015: \frac{28750 - 25000}{25000} \times 100 = 15\%
- 2016: \frac{31625 - 27500}{27500} \times 100 \approx 15.09\%
- 2017: \frac{44000 - 40000}{40000} \times 100 = 10\%
- 2018: \frac{38295 - 33300}{33300} \times 100 \approx 15\%
- 2019: \frac{39100 - 34000}{34000} \times 100 \approx 15\%
Item C does not maintain a consistent profit percentage either.
Item D:
- 2015: \frac{28750 - 25000}{25000} \times 100 = 15\%
- 2016: \frac{31900 - 27500}{27500} \times 100 = 16\%
- 2017: \frac{35100 - 30000}{30000} \times 100 = 17\%
- 2018: \frac{47200 - 40000}{40000} \times 100 = 18\%
- 2019: \frac{40460 - 34000}{34000} \times 100 \approx 19.06\%
Item D also does not maintain a consistent profit percentage.
Based on the calculations, Item A is the only item that maintains the same profit percentage on cost every year, which is consistently 15%.
