14. A number is divisible by 4 if the number formed by its last two digits is divisible by
4.
(i) Consider 45748
Number formed by last two digits is 48.
48 is divisible by 4.
Hence, 45748 is also divisible by 4.
(ii) Consider 21404
Number formed by last two digits is 04.
Now, 04 is divisible by 4.
Hence, 21404 is also divisible by 4.
15. Since ABCD is an isosceles trapezoidal, we have AD = BC.
Therefore, AD = BC = 4 cm.
Now the perimeter of given trapezium = AB + BC + CD + DA
= 12 + 4 + 8 + 4= 28
Hence, the perimeter of the given trapezium is 28 cm.
16. From the graph, it is clear that 5 students favoured orange and 1 student favoured
green.
Now, 5 – 1 = 4
Therefore, 4 more students favoured orange colour than green.

24. Number of vertices (V) = 8
Number of edges (E) = 12
Let, number of faces = F
Since every polyhedron satisfy Euler's formula, therefore
F + V = E + 2
Or, F + 8 = 12 + 2
Or, F = 14 - 8 = 6
Hence, the number of faces is 6.
