143

193

191

199

The hundreds digit is 1 because it is eight less than the tens digit. The tens digit is 9 because it is eight more than the ones digit. The ones digit is 3 because the difference between the ones and tens digits is six. Therefore, the correct answer is 193.

Explanation

The hundreds digit is 1 because it is eight less than the tens digit. The tens digit is 9 because it is eight more than the ones digit. The ones digit is 3 because the difference between the ones and tens digits is six. Therefore, the correct answer is 193.

13

The pattern in the series is that every alternate number is obtained by adding 2 to the previous number, while the other numbers are obtained by adding 4 to the previous number. Starting with 4, we add 2 to get 6, then add 4 to get 10, then add 2 to get 12, then add 4 to get 16. Therefore, the next number in the series would be obtained by adding 2 to 16, resulting in 18.

10. How long is an hour on Mars if a day is equivalent to two weeks on Earth? (Approx value)

16 Earth Hours

15 Earth Hours

20 Earth Hours

14 Earth hours

On Mars, a day is equivalent to two weeks on Earth. Therefore, if we divide 24 hours (a day on Earth) by 2, we get 12 hours. This means that a day on Mars is 12 hours long. Since the question asks for the length of an hour on Mars, we divide 12 hours (a Martian day) by 24 (an Earth day) to get 0.5. Therefore, an hour on Mars is 0.5 Earth hours. However, none of the given options match this calculation, so the correct answer is not available.
