A person invested Rs. 5000 in each of the years 2005, 2010, 2015 and 2020. The investment doubles every five years. What is the total amount the person will receive in 2025?
A1,35,000
B1,30,000
C1,50,000 ✓ Correct
D1,20,000
Correct answer: (C) 1,50,000
Explanation
The total received in 2025 is 1,50,000.
The 2005 deposit doubles four times: 5000 x 2^4 = 80,000.
The 2010 deposit doubles thrice: 5000 x 2^3 = 40,000.
The 2015 and 2020 deposits give 5000 x 2^2 = 20,000 and 5000 x 2 = 10,000.
Total = 80,000 + 40,000 + 20,000 + 10,000 = 1,50,000.
