Rs 2500 is lend partially on 8% and 5% at simple interest.  If after 3 years Rs.519 obtained as interest.  Then find the ratio of two parts of amount.

3 : 2 16 : 9 17 : 8 16 : 5

16 : 9

Total interest of 3 Years = 519 Total interest of 1 Year  = \(\frac{519}{3}\) Rate of total interest = \(\frac{519}{3}\) × \(\frac{100}{2500}\) = \(\frac{519}{75}\) = \(\frac{173}{25}\)% Now, ATQ Therefore, Ratio of two parts = 16 : 9
