Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 5650.
Given that,
Bank balance = 5000 for 25 days
Hence, the total balance in 25 days = 5000 × 25 = Rs.125000
Bank balance = 20000 for 2 days
Hence, the total balance in 2 days = 20000 × 2 = Rs.40000
Bank balance = 1500 for 3 days
Hence, the total balance in 3 days = 1500 × 3 = Rs.4500
Total balance for the month of June = 125000 + 40000 + 45000 = Rs.169500
Total days in June = 30
We know that,
Average = Sum of observations/Number of observations
Hence, average = = Rs.5650
Hence, the average balance (in ₹) in Rohit's bank account in June is Rs.5650.
