Question

find the rate of interest if the amount after 2 years of simple interest on a capital of Rs1200 is Rs 1440​

Answer 1

Answer:

10 %

Step-by-step explanation:

Given :- principal = 1200 RS

=> amout = 1440

=> time = 2 years

To find out => Rate %

Solution :-

interest = 1440-1200 = 240 rs

if we get 240 RS in two years then interest in one year = 240/2 = 120

Now we get 120 RS on 1200 in one year so

=> 120/1200×100

=> 10%

so rate is 10 %

Answer 2

Answer:

GIVEN: Amount=1440

Principal amount = 1200

simple interest =

Amount - p. a

1440 - 1200

240

simple interest = rs 240
