Solution:
Section to which the given problem relates: Section 17.
Case (a)

Case(b)
Decision:
This contract is not valid.
Reason:
It becomes Xs duty to tell V about the unsoundness of the horse because a fiduciary relationship exists between X and his daughter V. Here, X's silence is equivalent speech and hence amounts to fraud.
