Question

the simple interest on a certain sum of a money for 3 years at 8% per annum is half of the compound interest on ₹4000 for 2 years at 10% per annum what sum is placed on simple interest​

Answer 1

Answer:

Principle= Rs 4000

time=2 year

Rate=10%

Compound interest = P × ( 1 + r )n − P

I = P { ( 1 + r ) n − 1 }

I = 4000 ( 1 + .10)² − 1

I = 4000 ( 1.21 − 1 )

I = 840

AS per question,

Simple interest = 840 = 420 = PRT

2 100

So,

I = 420 = P × 0.08 × 3

I = Rs.1750

Answer 2

Step-by-step explanation:

Answer:

Principle= Rs 4000

time=2 year

Rate=10%

Compound interest = P × ( 1 + r )n − P

I = P { ( 1 + r ) n − 1 }

I = 4000 ( 1 + .10)² − 1

I = 4000 ( 1.21 − 1 )

I = 840

AS per question,

Simple interest = 840 = 420 = PRT

2 100

So,

I = 420 = P × 0.08 × 3

I = Rs.1750

I hope you get help.
