Study the given table and answer the question that follows.

The table presents the number of foreigners who arrived in India as tourists from five different countries over five years.

Countries Years ↓	USA	UK	UAE	China	Iran
2012	300	310	250	280	440
2013	480	420	280	320	400
2014	450	450	240	260	350
2015	320	380	300	400	380
2016	490	430	540	350	420

There was a 40% increase in the total number of tourists from all the countries together in 2017 as compared to 2016. If 1/7th of the total number of tourists in 2017 were from USA, how many tourists from USA visited India in 2017?

Correct option is C

Given:

Total tourists from all countries in 2016 =
USA: 490, UK: 430, UAE: 540, China: 350, Iran: 420
$$\frac17$$​th of total tourists in 2017 were from USA.

Solution:

Total = 490 + 430 + 540 + 350 + 420 = 2230

Increase in 2017 = 40% of 2230 = 0.40 × 2230 = 892
Total tourists in 2017 = 2230 + 892 = 3122
USA tourists in 2017 =$$\frac17$$ × 3122 = 446

446 tourists from USA visited India in 2017.
