Question

If the simple interest on a sum of 2 years at 10%p.a is Rs.1000 and the same amount is borrowed for 2 years at 8%p.a and compounded annually, then find the compound interest and theamout to be paid after 2 years.

Answer 1

a typing mistake = theamout should be the amount

Answer 2

on a sum of 2 years????

Answer 3

P * T * R
S.I. = --------
100
P * 2 * 10
1000 = ---------
100


1000 * 100
---------- = P
20

so P = 5000


Now put this P in the formula for compound interest and calculate.

If u need help, let me know...

Answer 4

do i need to find the amount after the principle

Answer 5

Use this formula for calculating amount

[ R ]^n
A = P [1 + ---- ]
[ 100 ] where n = no. of years

then C.I = A - P

Answer 6

i did the answer in this way, is it correct

P * T * R

S.I. = --------

100

P * 2 * 10

1000 = ---------

100
1000 * 100

---------- = P

20

P = 5000

A = 1000 + 5000
= 6000
According to the sum ow A becomes P
P = Rs.6000

[ R ]^n
A = P [1 + ---- ]
[ 100 ]
THEN A came as Rs.6,998.4
AND CI = 6,998.4 - 6000
= Rs.19948.4
Is it correct

Answer 7

"ow" moeans "now"

Answer 8

no this is wrong

first we find the P using the S.I. formula i.e. P = Rs. 5000

the question says "the same amount" which means the same P is borrowed on C.I.
so we have to use the same P i.e. Rs. 5000 in the formula for C.I.
