Question

Answer 1

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
