Question 990629
Let investment at 9.5% = x,
Total return = {{{(5000*6*1)/100 + (x*9.5*1)/100}}}
= {{{(30000 + 9.5x)/100}}} -----------------------(i)
Now for equivalent interest of 7%
Interest will be {{{((5000+x)*7*1)/100}}} --------(ii)
Equating (i) and (ii),
{{{(30000 + 9.5x) = (5000+x)*7*1}}}
{{{30000 + 9.5x = 35000 + 7x}}}
=> {{{x = 5000/2.5}}}
=> {{{x = 2000}}}
