Question

a person paid Rs6200 compound interest on a certain sum of money that he borrowed from a bank at 10%p.a.compunded annually for 1½ years.find the compound interest on the same sum and at the same rate for the same period of time,if the interest had to be paid semi-annually.​

Answer 1

Answer:

The formula is this P×R×T÷100=6200×10×1 1/2÷100

Step-by-step explanation:

So the answer is= 3410

Is it correct

Answer 2

Answer

semi - C. i = Rs. 6305

Step-by-step explanation:

given

C. I = Rs6200

T = 1 years ,6month

R= 10%

P=?

Semi - C. I = ?

we know,

C. I = P[(1+R\100) ^T x (1+ MR\1200) -1]

or, 2600= P [ (1+10\100)^1 (1+6x10\1200) -1]

or, 2600= P [ (1.1) (1260\1200) -1]

or, 2600= P [ (1.1)x(1.05)-1]

or, 2600= P [ 1.155 - 1]

or, 2600=0.155P

so, P = 2600/0.155

;. P = RS40,000

Again,

According by question,

semi - C. I = P[(1+R\200)^2T-1]

= 40000[(1+10\200) 2x3\2-1]

=40000[(1.05) ^3 -1]

=40000[ 1.157625- 1]

= 40000x 0.157625

= Rs.6305
