Answer»

Answer:

  • Simple Interest for 1 year on the same sum of money will be ₹300.

Step-by-step explanation:

Given that:

  • A sum of money AMOUNTS to ₹7200 in 4 YEARS.
  • The same sum of money amounts to ₹7800 in 6 years.

To Find:

  • Simple Interest on the sum for one year.

Solution:

Amount after the end of 4 years = ₹7200

Amount after the end of 6 years = ₹7800

Now,

Simple Interest of 2 years:

\sf{\longrightarrow(Amount\; after\; 6\; years) - (Amount \;after\; 4\; years)}

SUBSTITUTING the values,

\sf{\longrightarrow Rs.(7800-7200)}

Subtracting,

\sf{\longrightarrow Rs\;600}

Hence,

  • Simple Interest of 2 years = ₹600

As,

  • Simple Interest for 2 years is ₹600.

Therefore,

Simple Interest for 1 year = ₹600/2 = ₹300

Hence,

  • Simple Interest for 1 year = ₹300
