A group of friends visited the national zoological park, Delhi and at a particular time, they
observe that there are 100 legs and 72 eyes which they can view. They could recognise that
the legs and eyes they viewed were of tigers and parrots. One of them used the variables x
and y to represent the number of tigers and parrots respectively in the zoological park.
Then, another person formulated the linear equation for the total number of eyes they could
view as x + y = 6K. One more linear equation is formed for the number of legs as
2x + y = 50.
Based on the above information, answer the following questions:
(i) For what value of k will the point (8, 22) be the solution for equation of number of eyes?
(ii) How many solutions does the equation representing the number of legs have?
(iii) If k = 6 in the equation representing the number of eyes, then check if the points
(4, 32) and (21, 15) lie on the line or not.
OR
(iii) Write two solutions for the number of legs.

Bethany ordered satin balloons for the celebration of her brother?s birthday party. A packet
of satin balloons had conical and spherical shaped balloons, all of which were different in
colours. The packet also mentioned that the volume of air that is required to be filled in the
conical and spherical balloon is the same. Bethany measured the height of the conical
balloon, after it is filled with air, as 16 inches and its radius as 4 inches.
Another packet of satin balloons have hemispherical balloons with 4 times the radius of the
spherical balloons of the first packet.
A.What volume of air is to be filled in the spherical balloon
B.What is the radius of the spherical balloon after it is filled with air completely?
C.What will be the ratio of the total surface areas of the hemispherical balloons of the
second packet and spherical balloons of the first packet?
