$\huge\mathcal{\underline{\underline{{A}{\pmb{\sf{nswer \: : - }}}}}}$

The simple interest formula is given by :

• Simple interest = Principle  × rate/100 × time
• In simple interest the interest does not earn interest hence the amount increases by a constant amount every time.

From this information we can comfortably answer this question.

➫ Between year 5 and year 7 the amount increases by :

3000 - 2500 = 500

This is in a span of 2 years.

➫ The annual interest is given by:

➫ Annual interest = 500/2 = rs 250  

For 5 years the interest earned equals to :

➫ 250 × 5 = 1250.

The amount is thus :

➫ 2500 - 1250 = 1250

➫ The amount is thus : Rs 1250
