Question

a) Ram invested a certain amount of money for 3 years at 8% per annum. The simple
interest earned by him is half the compound interest on 24,000 for 2 years at 10% per
annum. Find the simple interest earned by Ram.​

Answer 1

Step-by-step explanation:

Lets find Amount on CI =

• Principle = 24000
• Rate % = 10%
• Time = 2 years
• Amount = ?
• CI = ?

$amount \: = p {(1 + r \div 100)}^{n}$

A = 24000( 1 + 10 / 100)^ 2

A = 24000( 11 / 10 )^ 2

A = 24000*11/10*11/10

A = 29040

$amount \: = principle + ci$

29040 = 24000 + CI

29040 - 24000 = CI

5040 = CI

SI is half of CI as per problem,

SI = CI / 2

SI = 5040 / 2

SI = 2520

Therefore, SI is rs. 2520
