Question

what sum of money lent out at 5% for 3years will produce the same intrest as rs 900 lent out at 4% for 5years

Answer 1

Simple interest = PxRxT/100

= 900X4X5/100

= 180 (simple interest)

let Principle is X

180=PxRxT/100

180= X x 5 x3/100

X = 1200

therefore the required sum of money is Rs 1200/-

Answer 2

Answer:

simply interest =P×R×T/100

=900 ×4×5×100

=108

180=P×R×T/100

108=Xx 5×3/100

x=1200

Rs.1200
