Interest in each case = 1750*6*10/100 = 1750*5*12/100 = Rs 1050 - 11 years agoHelpfull: Yes(9) No(16)
- Ans: Rs.1800
let p be the amount lent out
interest in 1st case= p*r*t/100
= p*6*t/100
=6pt/100------------------(equation 1)
interest in 2nd case= p*r*t/100
=p*5*(t+2)/100 (since recovered 2 years later than 1st one)
since amounts are equal(each 2880) and lent out sums are equal, intersts will be equal
=> 5p(t+2)/100=6pt/100
=>5t+10=6t
=>t=10yrs
final amt=2880
=>p + interst = 2880
=> p + 5p*12/100 = 2800
=>160p=2800*100
=> p= Rs.1750 - 11 years agoHelpfull: Yes(9) No(3)
