1)let the retail price is 100
then marketed price is 60
Eesha purchased at 60/2 = 30
so, the total discount is 70%

2)Anand, Bittu and Chandu finishes (73/81)*100 = 90% of the work in 6 days. The remaining 10% work can be done by Anand himself in one day. So,
the work will be completed on 7th day.

3)the road and the part of the trees make right angle triangle with base equal to breadth of the road and height equal to 36-h ft(if the tree breaks at h ft) and diagonal as h.
From h^2=(36-h)^2+12^2
we get h = 20ft

4)Since Peda can be eaten on the following day of Jilebi has eaten, It should not be eaten on MONDAY.

5)The answer is (a) 2,4,3,5,1 because
1 -typed - delivered
5 - typed -not delivered (in stack)
3 - typed - should be delivered because if it is kept in stack, the 4 has to be kept in stack before delivering 2.


6)M+D+I=74
M=D+46
I=0.4*D
solving, D=10 years

**the captain and vice-captain will be selected in 11C1*10C1=110

***The double century can be made in 17 ways. since the series we get to make double century with only sixes and fours as follows.
fours sixes
50 0
47 2
44 4
.. ..
2 32

Considering any arithmetic series, we get the answer as 17
