(d) Rs. 30,400
Show Answer & Explanation

Answer: (a) Rs. 28,500

Explanation:
1. Rs. 10,000 for 6 years: SI = 10000 × 18 × 6/100 = 10,800, amount 20,800
2. Rs. 5000 for 3 years: SI = 2700, amount 7700
3. Total = 20,800 + 7,700 = Rs. 28,500.

Teacher's Note:
1. Simple interest = P × R × T / 100, with T in years. Convert months into years by dividing by 12 before substituting.

Question 2: A sum was borrowed at 8% per annum and Rs. 138.75 interest was paid after 3 years 1 month. The sum borrowed was
(a) Rs. 450
(b) Rs. 600
(c) Rs. 625
(d) Rs. 562.50
Show Answer & Explanation

Answer: (d) Rs. 562.50

Explanation:
1. T = 37/12 years
2. P = 138.75 × 100/(8 × 37/12)
3. = 13875 × 12/296 = Rs. 562.50.

Teacher's Note:
1. Simple interest = P × R × T / 100, with T in years. Convert months into years by dividing by 12 before substituting.

Question 3: In what time will a sum of money at \( 13\frac{1}{3}\% \) simple interest triple itself?
(a) 7.5 years
(b) 15 years
(c) 20 years
(d) 10 years
Show Answer & Explanation

Answer: (b) 15 years

Explanation:
1. Interest earned = 2P
2. 2P = P × (40/3) × T/100
3. T = 200 × 3/40 = 15 years.

Teacher's Note:
1. Simple interest = P × R × T / 100, with T in years. Convert months into years by dividing by 12 before substituting.

Question 4: Find the simple interest when P = Rs. 600, R = 2% per annum and T = 20 months.
(a) Rs. 12
(b) Rs. 24
(c) Rs. 20
(d) Rs. 240
Show Answer & Explanation

Answer: (c) Rs. 20

Explanation:
1. T = 20/12 = 5/3 years
2. SI = 600 × 2 × (5/3)/100 = Rs. 20.

Teacher's Note:
1. Simple interest = P × R × T / 100, with T in years. Convert months into years by dividing by 12 before substituting.

Question 5: Find the principal when SI = Rs. 72, R = 3% per annum and T = 3 months.
(a) Rs. 2400
(b) Rs. 7200
(c) Rs. 960
(d) Rs. 9600
Show Answer & Explanation

Answer: (d) Rs. 9600

Explanation:
1. T = 1/4 year
2. P = 72 × 100/(3 × 1/4)
3. = 7200 × 4/3 = Rs. 9600.

Teacher's Note:
1. Simple interest = P × R × T / 100, with T in years. Convert months into years by dividing by 12 before substituting.

Question 6: Find the time when P = Rs. 640, R = 12.5% per annum and SI = Rs. 40.
(a) 1 year
(b) 6 months
(c) 3 months
(d) 9 months
Show Answer & Explanation

Answer: (b) 6 months

Explanation:
1. T = 40 × 100/(640 × 12.5)
2. = 4000/8000 = 1/2 year = 6 months.

Teacher's Note:
1. Simple interest = P × R × T / 100, with T in years. Convert months into years by dividing by 12 before substituting.

Question 7: Neeraj borrowed money at \( 10\frac{1}{2}\% \) per annum and paid Rs. 1863.75 interest for \( 2\frac{1}{2} \) years. The sum borrowed was
