A 5 m 60 cm high vertical pole casts a shadow 3 m 20 cm long. Find at the same time

(i) the length of the shadow cast by another pole 10 m 50 cm high


(ii) the height of a pole which casts a shadow 5m long.


(i) let the length of the shadow of other pole be x m


The given information in the form of table is as follows:


Length of shadow in m



3.20



x



Length of pole in m



5.60



10.50



The above information is in direct proportion.


3.20/5.60 = x/10.50


x = 6m


(ii) let the length of other pole be x m


The given information in the form of table is as follows:


Length of shadow in m



3.20



5



Length of pole in m



5.60



x



The above information is in direct proportion.


3.20/5.60 = 5/x


x = 8.75 m
