Answer 2

$\sf \frak \red{Answer:-}$

Given:

Principal (P) = Rs.400

Rate (R) = 0.2%

Time (T) = 6/12 or 1/2 year

Solution :

$\bf {S.I= \frac{P*R*T}{100} }$

$\: \: \: \: \: \: \: = \tt{ \frac{400 \times 0.2 \times (1 /2)}{100} }$

$\: \: \: \: \: \: \: \: = \tt{ \frac{ \cancel4 \cancel{00} \times \: 0 \cancel{. } \cancel2 \times 1 }{ \cancel{10 }\times \cancel 2 \times 1 \cancel{00} }}$

$\: \: \: \: \: \: \: \: = \tt{ \purple{ Rs \: 0.40} }$
