Seven chocolates: A, B, C, D, E, F and G.

Cost: 41, 42, 43, 45, 46, 47, 48, and 49 (none of the chocolates cost Rs. 44)

(1) The cost of chocolate C is Rs. 5 less than that of chocolate E, implies C = E - 5.

(2) The cost of chocolate A is a prime number.

(3) The cost of chocolate F is Rs. 2 more than that of chocolate A, implies F = A + 2.

Chocolates

Costs

A

41, 43, or 47

B

 

C

43, 42, or 41

D

 

E

48, 47, or 46
F 43, 45, or 49
G  

 

(4) The cost of chocolate F is more than that of chocolate E, implies F > E. Therefore, the cost of F is 49 and A is 47

(5) The cost of chocolate D is an odd number.

(6) The cost of chocolate G is Rs. 3 more than the cost of chocolate D, implies G = D + 3.

(7) The cost of chocolate B is an even number. Therefore, the final arrangement is as follows:

Chocolates

Costs

A

47

B

42

C

41

D

45

E

46
F 49
G 48

 

Hence, the cost of chocolate E is Rs. 46.
