please mark me as a brainiest

Step-by-step explanation:

915 in 3 years and to Rs. 854 in 4 years. So simple interest for 3 years will be =39×3=117 Rs.

Answer 2

Answer:

given that a sum of money at simple interest amounts to rs.915 in 3 years and to rs.854 in 4 years.

so, amount after 4 years= amount after 3years +simple interest in one year therefore, simple interest in one year

=954-915=rs.39

so simple interest for 3years will be

=39*3=rs.117

The initial sum money amount to be rs.915 in three years with simple interest.

therefore the principle is= amount- interest

=815-117=rs.698

therefore, the sum is rs. 698
