Answer 1

Given,

Principal = Rs. 50,000

Rate = 10% Per annum

Time = 2.5 years

We don't have to use the formula for Compound interest but we can use the formula of simple interest.


Now,

Principal ( P ) = Rs. 50,000

Rate ( r ) = 10% Per annum

Time ( t ) = 1 year

Simple interest = ( P × r × t ) / 100

= ( Rs. 50,000 × 10 × 1 ) / 100

= ( Rs. 500,000 ) / 100

= Rs. 5,000 ------- ( 1 )

Now, the Principal after 1 year will be ( Rs. 50,000 + Rs. 5,000 = Rs. 55,000 ).

Principal ( P ) = Rs. 55,000

Rate ( r ) = 10%

Time ( t ) = 1 year

Simple interest = ( P × r × t ) / 100

= ( Rs. 55,000 × 10 × 1 ) / 100

= Rs. 550,000 / 100

= Rs. 5,500 --------- ( 2 )

Now, Principal ( P ) = ( Rs. 55,000 + Rs. 5,500 = Rs. 60,500 )

Rate ( r ) = 10%

Time ( t ) = ( 1/2 ) years

Simple interest = ( P × r × t ) / 100

= ( Rs. 60,500 × 10 × 1 ) / ( 100 × 2 )

= Rs. 605 × 5

= Rs. 3,025 ------- ( 3 )

Adding ( 1 ) , ( 2 ) and ( 3 ),

= Rs. 5,000 + Rs. 5,500 + Rs. 3,025

= Rs. 13,525

Hence, Rs. 13,525 is the compound interest.
