उत्तर : 2. "Rs. 6540"
व्याख्या :
Answer: B) Rs. 6540 Explanation: Given C.I = 5984, R = 20% , T = 2yrs C.I = P1+201002-1 5984 = => P = (5995x25)/11 P = Rs. 13625 Now S.I = PTR/100 SI = (13625 x 8 x 6)/100 = Rs. 6540

उत्तर :
व्याख्या :
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.
