Question 1129956

{{{s = 750}}}
Rate of interest {{{ r= 6}}}% p.a. 
Principal = {{{p = 1250}}}$ (money deposited )
Let the time taken , {{{t }}}years 

By formula, 

{{{s=(p*r*t)/100 }}}

Thus, {{{s*100 = p*r*t }}} [ cross multiplication ] 

=>{{{(s*100)/(p*r) = t}}} [ dividing both sides by{{{ p*r }}}] 

=>{{{t = (750*100)/(1250*6)}}}
 
=>{{{t = 10 }}}

Thus, time taken is {{{10}}} years. ( ans. )
