Y = sin |x| satisfies the given graph. If x = 0, y = 0 If x = π/2, y = 1 If x = π, y = 0 If x = π/2, y = sin |-π/2| = sin π/2 = 1 If x = π, y = sin |-π| = 0 If x = 3π/2, y = sin |-3π/2| = -1 |
Directions : These questions are based on the data given below.
Solution.The number of toffees will be {(LCM of 4&5)k-1}i.e, 20k-1 since this is the number between 80 and 100, it can only be for k = 5 or 99 toffees.
If they are divided among 6 people, there will be three left.
Choice (3)

The party (even or odd) of the expression will be the same as that of the sum of the first n natural numbers.
Hence we need to check the party of n(n + 1)/2
n(n + 1)/2 is certainly even only when n is a multiple of 4 and for no other statement can a definite conclusion be drawn.
so Malini wins if n is a multiple of 4.
