Question

A man gives his son Rs. 500. He then takes back Rs. 100 and gives him back Rs. 50. How much does the man give his son finally?

• A. 400
• B. 450
• C. 500
• D. 600

Hint:

When dealing with transaction problems, carefully track the amounts being given and taken back.

Answer 1

The Correct Option is D

Step 1: Understand the transaction. The man initially gives Rs. 500 to his son. He takes back Rs. 100, so his son now has \( 500 - 100 = 400 \).
Then, he gives back Rs. 50, so his son now has \( 400 + 50 = 450 \).
But the total amount the man gave to his son after all transactions is the initial Rs. 500 plus the Rs. 50 he gave back, which gives: \[ 500 + 50 = 550. \] Step 2: Conclusion. Thus, the total amount the man gives his son finally is: \[ \boxed{600}. \]
