Question

rupees 4300 becomes rupees 4644 in 2 years at simple interest find the principal amount that will become rupees 10104 in 5 years at the same rate of interest​

Answer 1

Answer:

Given that money-years of (4300 x 2 = 8600) yield an interest of (4644 - 4300) = 344 Rs. By unitary method, (10104 x 5) will yield an interest of 344/8600 x (10104 x 5) = 2020.8, giving the final amount as 10104 + 2020.8 = 12124.8 Rs.
