Answer:
A traveler will need to visit a currency exchange because in different countries different currency is used for bought different items. so the traveler has to change their currency to that currency in which country he is travelling.
Explanation:
If a traveler has 100 US dollar and he travelling in India, he gets Rs 7554 in exchange of 100 US dollar, while if a traveler has 100 US dollar and he travelling in Canada, he gets 140 Canadian dollars in exchange of 100 US dollar. The cost of computer parts is same but only change that occurs due to the value of currency differences between different countries. If you buy computer parts, you will get it at the same price either you travel to Canada or to India to buy the part. In 2013, the products are less expensive due to high currency value which is decrease in 2020 so the price of products increases in 2020.
To solve the problem we will convert currencies and then solve the Problems.
Given to us
TPA, 1 USD = 1 TPA
CSW, 1 USD = 20 CSW
NRD, 1 USD = 5 NRD
Why use currency exchange?
1.) A traveler needs to visit a currency exchange to exchange his currency to the local currency of the country in which he is staying.
2.) We know that 1 USD = 20 CSW,
therefore, 100 USD = 20 x 100 = 2000 CSW.
Thus, your $100 will be equal to 2000 CSW dollars.
3.) We know that 1 TPA = 1 USD,
therefore, 100 USD = 100 x 1 = 100 TPA
Thus, your $100 will be equal to 100 TPA.
What is the cost of the computer part?
4.) We know that 1 USD = 1 TPA, while 1 USD = 20 CSW,
Given the cost of the computer part,
it will be 200 TPA = 200 USD,
it will be 1000 CSW = 50 USD,
Thus, the computer part will be cheaper, by 150 USD.
5.) As it is given that 1 USD = 3 NRD,
while now that 1 USD cost 5 NRD, therefore, now the same product will be cheaper.
For, example a product costing 300 NRD would be 100 USD last year but would cost only 60 USD now.
