Answer 1

Answer:

• ₹750 will amount to ₹1500 in 5 years and to ₹1200 in 3 years.

Step-by-step explanation:

Given that:

• A sum of money amounts to ₹1500 in 5 years and ₹1200 in 3 years.

To Find:

• The principal value.

Solution:

Amount for 5 years = ₹1500

Amount for 3 years = ₹1200

Simple Interest for 2 year = Amount for 5 years - Amount for 3 years

= ₹(1500 - 1200)

= ₹300

Simple Interest for 1 year = ₹(300/2)

= ₹150

Simple Interest for 3 years = ₹(150 × 3)

= ₹450

Principal = Amount - Simple Interest

= ₹(1200 - 450)

= ₹750

Hence,

• Principal = ₹750
