Answer 2

Principal (P)= 2400

Rate (R) = (7/5)%

Time (T) = 2 years four months= 7/3 years

$SI \: = \frac{P \times R \times T }{100} \\ \: \: \: \: \: \: \: = \frac{2400 \times 7 \times 7}{5 \times 100 \times 3} \\ \: \: \: \: \: \: \: = \frac{392}{5} \\ \: \: \: \: \: \: \: = 78.4$

Therefore, S.I.= 78.40
