Arun, Akash, Amir and Aswanth go for a picnic. When Arun stands on a weighing machine, Akash also
climbs on, and the weight shown was 132 kg. When Akash stands, Amir also climbs on, and the
machine shows 130 kg. Similarly the weight of Amir and Aswanth is found as 102 kg and that of Akash
and Aswanth is 116 kg. What is swanth’s weight?

• ans is 54 kg
  akash+arun=132....(1)
  akash+amir=130.....(2)
  akash+aswanth=116....(3)
  amir+aswanth=102....(4)
  sub (2) & (3)
  amir-aswanth=14....(5)
  solving (4) & (5) we get
  aswanth=54

• ans is 44
  akash + amir=130.......(1)
  amir + aswanth=102....(2)
  ashwanth +akash=116.......(3)
  add eq 2 & 3
  2aswanth+(amir+akash)=218.....(4)
  substitute 1 in 4
  then aswanth=44
