Direction (For next 2 questions): These questions are based on the following information: In a holy city, there are ten shrines and a certain number of holy lakes. A group of pilgrims stayed in the city for a few days and visited the shrines and lakes during their stay. At the end of the stay it turned out that in all each shrine was visited exactly by 4 pilgrims and each lake was visited exactly by 6 pilgrims. Each pilgrim visited exactly 5 shrines and 3 lakes. The number of lakes in the holy city is (a) 4 (b) 6 (c) 8 (d) 10

The number of edges of a triangular pyramid is (a) 3 (b) 4 (c) 6 (d) 8

Number of vertices of a cuboid is (a) 4 (b) 6 (c) 8 (d) 12

The product of the L.C.M. and H.C.F. of two numbers is 24. The difference of two numbers is 2. Find the numbers. (a) 2 and 4 (b) 6 and 4 (c) 8 and 6 (d) 8 and 10

Number of vertices of a cuboid is 4 (b) 6 (c) 8 (d) 12

If a group of n distinct objects, the number of arrangements of 4 object is 12 times the number of arrangements of 2 objects, then the number of objects is (a) 10 (b) 8 (c) 6 (d) none of these

If a group of n distinct objects,the number of arrangements of 4 object is 12 xx the number of arrangements of 2 objects,then the number of objects is (a) 10 (b) 8(c)6(d) none of these
