Answer 1

The compound interest on a certain sum at 16 3 2 % per annum
what is 16 here

Answer 2

X is principle

R - 50/3%, T= 3 years & Compound Interest = Rs.12,700

Then, 12,700 = {X(50/3×100 + 1)3 – X}

12,700 = 343 X/216 – X

12,700 = (343 X – 216 X)/216

X = 21600

Here is the simple interest of given Rs.21,600 is 21,600 x 3 x 50 /3 x 100

= 216 x 50

Simple interest is= 10,800
