Answer 1

Q. Find the compound interest on ₹ 25,000 at the rate of 12 % per annum for 3 years( as told ).

Given, principal = ₹ 25,000

rate = 12 % p.a , time = 3 yrs

Find the amount :
-----------------------
amount = p [ 1 + ( r/100 ) ]^t

amount = 25,000 [ 1 + ( 12/ 100) ]^3

amount = 25000( 112/100 )^3

amount = 25000( 56/50)^3

= 25000 × 56/ 50 × 56/ 50 × 56/ 50

=( 25 × 56 × 56 × 56 ) / 125

= (56 × 56 × 56 ) / 5

= 175616 ÷ 5 = ₹35123.2

Find the compound interest :
---------------------------------
C.I = amount - principal

C.I = ₹35123.2 - 25,000 = ₹10,123.2

therefore,

the compound interest = ₹10,123.2

Answer : C.I = ₹10,123.2
