A school has received 60% of the amount it needs for a new building by receiving a donation of $300 each from people already solicited. People already solicited represent 40% of the people from whom the school will solicit donations. How much average contribution is requited from the remaining targeted people to complete the fund raising exercise?	Select.
A) $200
B) $177.78
C) $100
D) $277.78
E) $377.78
Let the amount school needs = X   Let total people school plans to solicit = T   School has received 60 % of X =&gt; (3/5) X   People already solicited = 40% of T =&gt; (2/5) T   Now, as per the information given in the question :   (3/5)X = $400 . (2/5) . T --------------------------- 1   Remaning Amount is 40 % i.e ( 2/5 ) X ------because school has already received 60%   And the remaining people are 60 % i.e (3/5) .T -----because 40% of the people are already solicited   So, average contribution required from the remaining targeted people is   (2/5) X = (Amount required) . (3/5) . T ----------------------------------- 2   Divide eqn 1 by eqn 2   Amount required = $177.78   $177.78
