Each of A, B, C and D has Rs 100. A pays Rs 20 to B, who pays Rs 10 to C, who gets Rs 30 from D. In this context, which one of the following statements is not correct?
- AC is the richest
- BD is the poorest
- CC has more than what A and D have togetherCorrect
- DB is richer than D
Explanation
Let's track the money each person has after the transactions:
Initial amounts: A = 100 B = 100 C = 100 D = 100
-
A pays Rs 20 to B: A = 100 - 20 = 80 B = 100 + 20 = 120 C = 100 D = 100
-
B pays Rs 10 to C: A = 80 B = 120 - 10 = 110 C = 100 + 10 = 110 D = 100
-
C gets Rs 30 from D: A = 80 B = 110 C = 110 + 30 = 140 D = 100 - 30 = 70
Final amounts: A = 80 B = 110 C = 140 D = 70
Now let's analyze each statement:
A) C is the richest: C has 140, which is the highest amount. This statement is CORRECT. B) D is the poorest: D has 70, which is the lowest amount. This statement is CORRECT. C) C has more than what A and D have together: C has 140. A and D together have 80 + 70 = 150. 140 is NOT more than 150. This statement is NOT CORRECT. D) B is richer than D: B has 110, D has 70. 110 is greater than 70. This statement is CORRECT.
The question asks for the statement that is NOT correct. Therefore, option C is the answer.
The final answer is C
