1. The interest on a certain deposit at 4.5% p.a. is TK. 202.50 in one year. How much will the additional interest in one year be on the same deposit at 5% p.a. ?
- A. TK. 22.50
- B. TK. 22.50
- C. TK. 22.50
- D. TK. 22.50
Answer: Option A
Explanation:
For 4.5% p.a
I = pnr/100
P = I × 100/nr = ( 202.50 × 100)/( 1× 4.5) = 4500
for 5% p.a
I = pnr
= 4500 × 1 × 5/100 = 225
The total additional interest = ( 225 - 202.50)Tk. = 22.50tk.
