Question

the sum required to earn a monthly interest of 1200ruppes at 18% p.a SI is ​

Answer 1

Answer:

Step-by-step explanation:

SI = (P*T*R)/100

let principle = x

time = 1yr

Rate of interest = 18%

SI = 1200

SI = PTR/100

1200 = X *1*18/100

X=1200*100 / 18*1

Principle = X = 6,667 RS

Answer 2

Answer: yo bro pls mrk me dear friend

SI = P x ROI x T & Amount (return) = P + SI

i.e. at the end of 1st year

SI = 1000 x 10% x 1 = 100 & Principle for 2nd year 1000 + 100 = 1100

Now, in similar manner, interest has to be calculated & at maturity the amount will be as ₹1210

SI = 1100 x 10% x 1 = 110 & Amount = 1100 + 110 = 1210

hope it helps brother
