राजीव, संजीव और विजय दौड़ती हुई दौड़ में शामिल होते हैं। दूरी 1500 मीटर है। राजीव ने संजीव को 30 मीटर और विजय को 100 मीटर से हराया। यदि वे दोनों पहले की तरह दौड़े तो संजीव विजय को कितनी दूर से हरा सकता है?

SHOW ANSWER
  Answer 3
Explanation: Sanjiv runs 1470 metres while Vijay runs 1400 metres.
Sanjiv speed as compare of Vijay= 1400/1470
At the same rate Sanjiv runs 1500 metres whilst Vijay runs 1500 x 1400 / 1470 Meters Or 1428.6 metres
Hence Sanjiv ought to beat Vijay by 71.4 metres.

1²+ 2² + 3² + 4²= 1 + 4 + 9 + 16 = 30
1²+ 2² + 3² + 4² + 5²= 55
1²+ 2² + 3² + 4² + 5² + 6² = 91
50 is not correct in series
