5.(b) : In the figure CD is tower and AB is hill on the same plane

In  ACD, tan 300 = CD/AD
1/√3 = 50/AD   AD = 50√3
In  ABD, tan 600 = AB/AD √3 h/50√3  h= √3 x 50√3 = 150 m.
Height of the hill AB = 150 m.

7.(c) : Amount Earned by P,Q and R in 1 day = 1620/9 = 180 —(1)
Amount Earned by P and R in 1 day = 600/5 = 120 —(2)
Amount Earned by Q and R in 1 day = 910/7 = 130 —(3)
(2)+(3)-(1) => Amount Earned by P , Q and 2R in 1 day 
– Amount Earned by P,Q and R in 1 day = 120+130-180 = 70
=>Amount Earned by R in 1 day = 70

8.(d) : Let original length = 100 and original breadth = 100
Then original area = 100 × 100 = 10000
Length of the rectangle is halved ⇒New length = Original length/2=100/2=50
breadth is tripled ⇒New breadth= Original breadth×3=100×3=300
New area = 50 × 300 = 15000
Increase in area = New Area – Original Area = 15000 – 10000= 5000
Percentage of Increase in area =( Increase in Area)/ (Original Area)×100= (5000)/10000) ×100=50%
