If the stay of 6 men for 14 days in a hotel costs Rs.3360, find the cost for stay of 4 men for 7 days in the same hotel?
Correct answer: B. 1120
- A. 823
- B. 1120
- C. 1372
- D. 2520
Explanation
In the question, we are given that it costs Rs. 3360 for 6 men to stay at a hotel for 14 days. We would like to find out the cost of staying at the hotel for one man for one day. If 6 men were to stay at the hotel for one day, the cost would be 3360 / 14 = Rs. 240. If 1 man was to stay at the hotel for one day, the cost would then be 240/6 = Rs. 40. We now know that the cost to stay at the hotel is Rs. 40 per day per person. To find the total cost for 4 men staying for 7 days, we multiply these numbers by the cost to stay at the hotel per day per person. 40x4x7 = Rs. 1120. Therefore B is the correct answer.
