"hi guys welcome to lido q a video
i am vinit your leader tutor bringing
you this question on your screen
a sum of rupees 9600 is invested for
three years
at ten percent per annum at compound
interest
what is the sum due at the end of first
year
so for number one principle is nine
thousand
600 rate is
10 percent and
time is 1 year
therefore sum due
at end of
one year is given by
principle into 1 plus r by 100
by t to 9
600 into 1 plus
10 by 100
to the power one so this is nine
thousand
six hundred into eleven by ten
right so let us multiply nine thousand
six hundred
so 0 right 6
9 6 15 5 1.
so rupees 10 560.
that's our first answer
now number two
what is the sum due at the end of second
year again
for the second year principal will be
the amount of
first year r
is is the same and time is again 1 year
therefore amount
due at the end of second year will be
equal to
10 560 again into
11 by 10 right
so 1 0 5 6 into 11 gives us
so piece 1 1 6 1
6 let us look at the third one
find the compound interest earned in two
years
right so
compound interest
earned in two years
will be equal to amount
at the end of two years right
minus principle
so this is equal to what is the amount
at the end of two years
eleven thousand six hundred and sixty so
rupees
eleven thousand six hundred and sixteen
minus
nine thousand six hundred so this is
equal to rupees
2016
right it's not easy now let us look at
number four
find the difference between the answers
in two and one and find the interest
on this sum for one year
so difference
is equal to
11615 minus
so 616 minus
10560
right so this will be equal to rupees
6 5 0
1 6
interest on rupees
1056 for one year
is given by 1 0 5 6 into
again 11 by 10
right so that will be equal to
okay this is not uh into 11 by 10
but yeah
so this is the amount so this will be
equal to
1161.6
therefore interest
is equal to rupees 5.6
and lastly number five
compound interest for the third year so
amount for the third year
is equal to eleven thousand hundred 616
right into 11 by 10 that is equal to
one thousand twelve thousand seven
hundred and seventy seven point
six therefore
interest will be equal to
interest will be equal to
one two seven seven seven
point six minus one one
six one six that will be equal to
one six
one one one six
one point six right guys
so isn't that isn't that easy right
so yeah if you have a doubt please leave
