If A runs less fast than B, and B runs as fast but not faster than C; then, as compared to A, C runs

Correct Option (2)

Let S_A, S_B, and S_C represent the speeds of A, B, and C, respectively.

• The statement "A runs less fast than B" implies that B's speed is greater than A's speed: S_B > S_A.
• The statement "B runs as fast but not faster than C" implies that B's speed is equal to C's speed: S_B = S_C.

By substituting S_C for S_B in the first inequality, we derive S_C > S_A. This indicates that C runs faster than A.

Incorrect Options:

• Option 1 (slower than A): This is incorrect because the derived relationship S_C > S_A clearly indicates that C's speed is greater than A's speed, not less.
• Option 3 (with same speed as A): This is incorrect because the derived relationship S_C > S_A shows that C's speed is strictly greater than A's speed, not equal.
• Option 4 (Given data is not sufficient to determine): This is incorrect as the provided conditions establish clear inequalities and equalities that permit a definitive conclusion regarding the comparative speeds of A and C.
