Question 1.

At a rate of 10 p.c.p.a., what would be the interest for one year on Rs 6000?

Solution:

Principal Amount = Rs 6000

Rate of Interest = 10 p.c.p.a.

Let interest on principal Rs 6000 be Rs x.

By taking ratio of the interest to the principal for both, we obtain an equation x 10

∴ The interest for one year is Rs 600.

Question 2.

Mahesh deposited Rs 8650 in a bank at a rate of 6 p.c.p.a. How much money will he get at the end of the year in all?

Solution:

Principal Amount = Rs 8650

Rate of interest = 6 p.c.p.a.

Let interest on principal Rs 8650 be Rs x

By taking ratio of the interest to the principal for both, we obtain an equation

∴ Amount received at the end of the year = Principal amount + Interest

= Rs 8650 + Rs 519

= Rs 9169

∴ Mahesh will get Rs 9169 at the end of the year.

Question 3.

Ahmad Chacha borrowed Rs 25,000 at 12 p.c.p.a. for a year. What amount will he have to return to the bank at the end of the year?

Solution:

Principal Amount = Rs 25,000

Rate of interest = 12 p.c.p.a.

Let interest on principal Rs 25,000 be Rs x

By taking ratio of the interest to the principal for both, we obtain an equation

Amount to be returned to the bank at the end of the year = Principal Amount + Interest

= Rs 25,000 + Rs 3,000

= Rs 28,000

Ahmad Chacha has to return Rs 28,000 to the bank at the end of the year.

Question 4.

Kisanrao wanted to make a pond in his field. He borrowed Rs 35,250 from a bank at an interest rate of 6 p.c.p.a. How much interest will he have to pay to the bank at the end of the year?

Solution:

Principal Amount = Rs 35,250

Rate of interest = 6 p.c.p.a.

Let interest on principal Rs 35,250 be Rs x

By taking ratio of the interest to the principal for both, we obtain an equation
