Answer:
(a) $75
(b) $30
(c) $80
(d) $56
Explanation:
(a) Principal amount p = $5000
Rate of interest r = 6 %
Time t = 90 days [tex]=\frac{90}{360}=0.25years[/tex]
We know that simple interest [tex]=\frac{principal\ amount\times rate\times time}{100}=\frac{5000\times 6\times 0.25}{100}=$75[/tex]
(b) Principal amount p = $800
Rate of interest r = 9 %
Time t = 5 month [tex]=\frac{5}{12}=0.4166years[/tex]
We know that simple interest [tex]=\frac{principal\ amount\times rate\times time}{100}=\frac{800\times 9\times 0.4166}{100}=$30[/tex]
(c) Principal amount p = $6000
Rate of interest r = 8 %
Time t = 60 days [tex]=\frac{60}{360}=0.1666years[/tex]
We know that simple interest [tex]=\frac{principal\ amount\times rate\times time}{100}=\frac{6000\times 8\times 0.1666}{100}=$80[/tex]
(d) Principal amount p = $1500
Rate of interest r = 7 %
Time t = 6 months [tex]=\frac{6}{12}=0.5years[/tex]
We know that simple interest [tex]=\frac{principal\ amount\times rate\times time}{100}=\frac{1600\times 7\times 0.5}{100}=$56[/tex]
