Detailed Solution
Download Solution PDFGiven:
Additional deposit = ₹50,000
Simple Interest (SI) = ₹7,500
Rate of Interest (R) = 4.5% per annum
Time (T) = 1 year
Formula Used:
Simple Interest (SI) = Principal (P) × Rate (R) × Time (T) / 100
Calculation:
Let the initial amount in the account be ₹X.
Total Principal (P) = X + 50,000
SI = (X + 50,000) × 4.5 × 1 / 100
7,500 = (X + 50,000) × 4.5 / 100
⇒ 750,000 = 4.5X + 225,000
⇒ 750,000 - 225,000 = 4.5X
⇒ 525,000 = 4.5X
⇒ X = 525,000 / 4.5
⇒ X = 116,666.67
The initial amount already in the account is ₹1,16,666.67.
