Answer : 1. "90"
Explanation :
Answer: A) 90 Explanation: Let the least value of the prize = Rs. x Then the next value of the prize is x+30 , x+60, x+90, ....x+240. Given total amount of cash prizes = Rs.1890 --> x + (x+30) + (x+60) + (x+90) + ....+ (x+240) = 1890 --> 9x + (30 + 60 + 90 + 120 + 150 + 180 + 210 + 240) = 1890 --> 9x + 30(1 + 2 + 3 + 4....+ 8) = 1890 --> 9x + 30(36) = 1890 --> 9x = 810 --> x=90 Hence the least value of the prize x=90

Answer : 3. "35 days"
Explanation :
Answer: C) 35 days Explanation: Distance d = 1200kmlet S be the speed he walks 15 hours a day(i.e 24 - 9)so totally he walks for 70 x 15 = 1050hrs. S = 1200/1050 => 120/105 = 24/21 => 8/7kmph given 1 1/2 of previous speedso 3/2 * 8/7= 24/14 = 12/7 New speed = 12/7kmph Now he rests 10 hrs a day that means he walks 14 hrs a day. time = 840 x 7 /12 => 490 hrs=> 490/14 = 35 days So he will take 35 days to cover 840 km.
