Question

Find the amount to be paid at the
end of three years in each case:
a. Principal rupees1200 at 12% per annum
b. Principal rupees7500 at 5% per annum

Answer 1

Answer:

a) Rs 1632 b) Rs 8625

Step-by-step explanation:

First of all, please specify whether it is simple interest or compound interest.

Assuming it is simple interest,

a) Given that,

Principal(P) = 1200, Rate(R) = 12, Time(T) = 3 yrs

Thus Simple interest SI = PRT/100

SI = (1200)(12)(3)/100

=  432

Amount = Principal + SI

= 1200+432 = Rs 1632

b)   P = 7500, R = 5, T = 3

SI = PRT/100

SI = (7500)(5)(3)/100

= 1125

Amount = P+SI

=7500+ 1125 = Rs 8625
