The average weight of D, E and F is 42 kg. If the average weight of D and E be 35 kg and that of E and F be 41 kg, what is the weight of E?	Choose the correct choice from the following answers.
A) 23 Kg  B) 24 Kg  C) 25 Kg  D) 26 Kg  E) 27 Kg
Let the weight of D, E and F are a,b and c respectively.   Average weight of 26 Kg,E and F = 42   a + b + c = 42 × 3 = 126 --- equation(1)   Average weight of 26 Kg and E = 35   a + b = 35 × 2 = 70 --- equation(2)   Average weight of E and F = 41   b + c = 41 × 2 = 82 --- equation(3)   equation(2) + equation(3) - equation(1)   =&gt; a + b + b + c - (a + b + c) = 70+82 - 126   =&gt; b = 152-126=
