Answer» time = (90100)/(7504) = 3yearsSum = (100amount)/(100+rt) = (100575)/(100 + 35) = ₹ 500 There is a direct relationship between the principal and the amount and is given by SUM = (100Amount)/(100+rt)

24, A certain sum of money amounted to Rs 575 at 5% in a time inwhich Rs 750 amounted to Rs 840 at 4%. If the rate of interest issimple, find the sum.

Answer»

time = (90*100)/(750*4) = 3yearsSum = (100*amount)/(100+rt) = (100*575)/(100 + 3*5) = ₹ 500

*There is a direct relationship between the principal and the amount and is given by SUM = (100*Amount)/(100+rt)*
