**Question 1.**

**Solution:**

Principal (p) = Rs. 2500

Rate (r) = 10% p.a.

Period (t) = 2 years

Interest for the first year = \(\\ \frac { prt }{ 100 } \)

= \(\\ \frac { 2500X10X1 }{ 100 } \)

= Rs. 250

Amount at the end of first year = Rs. 2500 + Rs. 250

= Rs 2750

Principal for the second year = Rs 2750

Interest for the second year = Rs \(\\ \frac { 2750X10X1 }{ 100 } \)

= Rs. 275

Amount at the end of second year = Rs 2750 + Rs. 275

= Rs. 305

and compound interest for the 2 years = Rs. 3025 – Rs. 2500

= Rs 525 Ans.

**Question 2.**

**Solution:**

Principal (P) = Rs. 15625 Rate

(R) = 12% p.a.

Period (n) = 3 years

**Question 3.**

**Solution:**

Principal (P) = Rs. 5000

Rate (R) = 9% p.a.

Time (n) = 2 years

**Question 4.**

**Solution:**

Amount of loan (p) = Rs. 25000

Rate of interest (r) = 8% p.a.

Period (t) = 2 years

**Question 5.**

**Solution:**

In case of Harpreet :

Amount borrowed by Harpreet (P) = Rs. 20000

Rate (r) = 12%

Period (t) = 2 Years

**Question 6.**

**Solution:**

Principal (p) = Rs. 64000

Rate (r) = \(7\frac { 1 }{ 2 } \) = \(\\ \frac { 15 }{ 2 } \)%

Period (t) = 3 years

Interest for the first year = \(\\ \frac { prt }{ 100 } \)

= Rs \(\\ \frac { 64000X15X1 }{ 100X2 } \)

= Rs 4800

= Rs 79507

**Question 7.**

**Solution:**

Principal (p) = Rs 6250

Rate (r) 8% p.a. or 4% half yearly

Period (t) = 1 year = 2 half years

**Question 8.**

**Solution:**

Principal (p) = Rs. = 16000

Rate (r) = 10% p.a. or 5% half yearly
