A Bank lends Rs, 30,00,000/- to a person P at 12.5% simple interest and Rs. 10,00,000/- to another person Q at 10.5% simple interest, for t years. If the Bank received an interest of Rs. 16,80,000/- at the end of the period t, then t =

Solution

Interest received from first person = 3000*125*t = 3,75,000*t rupees
Interest received from second person = 1000*105*t = 1,05,000*t rupees

3,75,000t*t + 1,05,000*t = 16,80,000
4,80,000*t = 16,80,000
t = 3.5
