 One more question of the same type (Same type of diagram; of course 
in a different    set)

Time and Work
1.A man, a woman, and a child can do a piece of work
in 6 days. Man only can do it in 24 days. Woman can do
it in 16 days and in how many days child can do the 
same work? (Numbers are not correct. Problem model is
important)

2.A and B can do a piece of work in 14 days.  A is twice as efficient 
as B. how long will A alone take?
3.A, B, C can do a work in 6 days.  A can do in 10 days.  B in 24 days 
then how many days C will take?
4.A can do a work in 12 days. B can do in 9 days. A worked for 5 days 
and left. How long will B take to complete?

6)In Madras, temperature at noon varies according to
-t^2/2 + 8t + 3 (READ as: -t square /2 +...), where
t is elapsed time. Find how much temp rise or fall in
4pm to 9pm. (May be we can solve it by Definite
Integration. Check any way)
     8) Same as before for T^2/9  + 4T   + 16    
7)N=15*28*36      which of the following are integers?    N/15, N/32,?
. 
8)For Aeroplane sum answer is either 4 pm or 4 am.
9) A power unit is there by the bank of the river of 900 mtr width.  A 
cable is made from power unit to power a plant opposite to that of the 
river and 3000 mtr away from the power unit.  The cost of the cable 
bellows water Rs.5 per mtr and cost of the cable on the bank is Rs.4 
per mtr.  Find the total of laying the cable.
Ans:   900*4  +  (3000-900)*5  =  14100
