Answer : 2. "397"
Explanation :
Answer: B) 397 Explanation: The pattern of given series is : 5 14 = (5x3) - 1 45 = (14x3) + 3 130 = (45x3) - 5 (?) = (130x3) + 7 => (?) = 397 1182 = (397x3) - 9 Thus, the missing number is 397.

Answer :
Explanation :
1. How to find Speed(s) if distance(d) & time(t) is given: Speed (S) = Distance (D)Time (T) Ex: Find speed if a person travels 4 kms in 2 hrs? Speed = D/T = 4/2 = 2 kmph. 2. Similarly, we can find distance (d) if speed (s) & time (t) is given by Distance (D) = Speed (S) x Time (T) Ex : Find distance if a person with a speed of 2 kmph in 2 hrs? Distance D = S X T = 2 x 2 = 4 kms. 3. Similarly, we can find time (t) if speed (s) & distance (d) is given by Time (T) = Distance (D)Speed (S) Ex : Find in what time a person travels 4 kms with a speed of 2 kmph? Time T = D/S = 4/2 = 2 hrs. 4. How to convert km/hr into m/sec : P km/hr = P x 518 m/sec Ex : Convert 36 kmph into m/sec? 36 kmph = 36 x 5/18 = 10 m/sec 5. How to convert m/sec into km/hr : P m/sec = P x 185 kmph. Ex : Convert 10 m/sec into km/hr? 10 m/sec = 10 x 18/5 = 36 kmph. 6. If the ratio of the speeds of A and B is a:b, then the ratio of the times taken by them to cover the same distance is b : a. 7. Suppose a man covers a certain distance at x km/ hr and an equal distance at y km/hr . Then, the average speed during the whole journey is 2xyx+y km/hr.

Answer : 3. "Joules"
Explanation :
Answer: C) Joules Explanation: Energy is measured in units called Joules. Joule is unit of work or energy in the International System of Units (SI) which is equal to the work done by a force of one newton acting through one metre. 1 Joule = 107 ergs or 0.7377 foot-pounds.
