a+b = 67
b+c = 76
c+d = 93
d+e = 107
adding all of them , a + e + 2( b+c+d) = 343 ---(1)
given , a+e = 215 - (b+c+d) ----(2)
comparing (1) and (2) ==> b+c+d = 128 .----(3)
==> b= 128 - ( c+d) = 128-93=35
similarly , d= 52 .
now from (3) , c= 128 -(b+d) ==> 128-87 => 41 .
d+e ==> 52 +e ==> 107 ==> e = 55
now substitute these on (2) ==> a = 215-(b+c+d+e) ==> 215-(52+35+41+55) ==> 215-183 ==>a= 32.
