25. A manufacturing company makes two types of teaching aids A and B of Mathematics for
class XII. Each type of A requires 9 labour hours of fabricating and 1 labour   hour   for
finishing.   Each   type of B requires 12  labour  hours  for  fabricating and  3  labour  hours
for  finishing.   For fabricating and finishing, the maximum labour hours available per week
are 180 and 30 respectively. The company makes a profit of 80 on each piece of type A and
120 on each piece of type B. How many pieces of type A and type B should be manufactured
per week to get a maximum profit? Make it as an LPP and solve graphically.   What is the
maximum profit per week?

26. There are three coins. One is a two-headed  coin (having  head  on both faces), another is a
biased coin that  comes up heads  75% of the times and third  is also a biased coin that
comes up tails 40% of the times. One of The three coins is chosen at random and tossed,
and it shows heads.  What is the probability that it was the two-headed coin?
OR
Two numbers are selected at random (without replacement) from the first six positive
integers.  Let X denote   the   larger of the   two numbers obtained.  Find the probability
distribution of the random variable X, and hence find the mean of the distribution.

27. Two schools A and B want to award their selected students on the values of sincerity,
truthfulness and helpfulness.  The school A wants  to  award x each,  y each and z each for
the  three  respective  values to 3, 2 and 1 students respectively  with a total  award  money
of 1,600. School B  wants   to  spend  2,300  to  award   its  4,  1 and  3  students on  the
respective values (by giving the same award  money to the three values as before). If the
total amount for one prize on each value is 900, using matrices, find the award money for
each value. Apart  from  these three  values,  suggest  one  more  value  which  should  be
considered  for award.
