Answer 1

Step-by-step explanation:

P=rs 46,875

T= 1yr+8months= 1+8÷12 =5/3 yr

si=50000-46875=3125

$r = \frac{100 \times si}{p \times t}$

=100×3125×3/46875×5

=4% ans.

Answer 2

The rate of interest is 4%

Step-by-step explanation:

Princiapal = Rs.46875

Amount = Rs.50000

Interest = Amount - Principal = 50000-46875=Rs.3125

Time = 1 year 8 months =$1 + \frac{8}{12} =\frac{20}{12} years$

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

P = Principal

T= time

R = rate of interest

So, $3125 = \frac{46875 \times \frac{20}{12} \times R}{100}\\\\\frac{3125 \times 100 \times 12}{46875 \times 20}=R\\\\4\%=R$

Hence The rate of interest is 4%
