Answer 2

Answer:

The simple interest and amount is Rs.20.7123 and Rs.1220.7123 respectively

Step-by-step explanation:

Days from 8 April to 20 June = 42 day

Principal = Rs.1200

Rate of interest = 15%

$SI = \frac{P \times R \times T }{100}$

$SI = \frac{1200 \times 15 \times 42}{365 \times 100}$

$SI = 20.7123$

Amount = Principal + SI = 1200+20.7123 = Rs.1220.7123

Hence The simple interest and amount is Rs.20.7123 and Rs.1220.7123 respectively
