Question

Rockey has lent out 8000 for 5 years
at 15% per nm & borrowed ruppies 6000
for 3 years at 12% per nm, how much
did he gain or loose.

Answer 1

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

$SI=\frac{8000*15*5}{100}$

     $=Rs. 6,000$

Amount = $8,000+6,000=Rs. 14,000$

Interest = $Rs. 6,000$ Amount = $Rs. 14,000$

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

$SI=\frac{6000*12*3}{100}$

     $= Rs.2160$

Amount = $6,000+2,160=Rs.8,160$

Interest = $Rs. 21,600$  Amount = $Rs.8160$

Gain: 6,000 - 2,160

Gain = Rs. 3,840

hope this helps......
