  1. admin Says:

    1. Ans. a. — From statement A.

    2. Ans. b. — From both statements individually. If x is the number of tosses he took, from statement I we get the equation 10 + x –100 = 50. Thus x = 140. From statement II individually, we have x > 138. Thus we are sure he has paid up more than 148. If he incurs a loss of only Rs. 50, the game has to end normally. Thus the above state of his taking 150 shots with first 138 as tails and 139 and 140 throw as tails is the scenario. With no other scenario will a loss of just 50 and 138 tails show up.

    3. Ans. c. — Using both statements.

    4. Ans.c. — Using both statements.
