After a certain number of years, however, the rate of interest has been reduced to 7%. It is also known that at the end of the agreed period, he will have paid in all Rs.2,70,900 in interest.

A. 10 years

B. 12 years

C. 13 years

D. 14 years

E. None of the Above

###### Answer & Explanation

**D. 14 years**

**Explanation:**

x = interest paid at 7.5%

(21-x) years interest paid at 7%

((180000*x*7.5)/100) + ((180000*7*(21-x))/100) = 270900

x = 7

21 – 7 = 14 years he paid at the reduced interest rate.**Ankita borrows Rs.7000 at simple Interest from a lender. At the end of 3 years, she again borrows Rs.3000 and settled that amount after paying Rs.4615 as interest after 8 years from the time she made the first borrowing. what is the rate of interest?**

A. 5.5%

B. 9.5%

C. 7.5%

D. 6.5%

E. None of the Above

###### Answer & Explanation

**D. 6.5%**

**Explanation:**

SI for Rs.7000 for 8 years= (7000*r*8)/100

Again borrowed=3000

SI = (3000*r*5)/100

Total interest= [(7000*r*8)/100] + [(3000*r*5)/100] = 4615

560r + 150r = 4615

710r = 4615

r = 6.5%**Hari borrowed some money for one year at 6% per annum simple interest and after 18 months , he again borrowed the same money at a Simple Interest of 24% per annum. In both the cases, he paid Rs.4704. Which of the following could be the amount that was borrowed by Hari in each case if interest is paid half yearly?**

A. 4000

B. 3000

C. 4400

D. 4200

E. None of the Above

###### Answer & Explanation

**D. 4200**

**Explanation:**

12% for 6 months

x = Borrowed money

Take x =100%

112% of x = 4704

x = 4200**Ravi lent out a part of Rs. 38800 is lent out at 6% per six months. The rest of the amount is lent out at 5% per annum after one year. The ratio of interest after 3 years from the time when first amount was lent is 5:4. Find the second part that was lent out at 5%.**

A. 28500

B. 30080

C. 20500

D. 28800

E. None of the Above

###### Answer & Explanation

**D. 28800**

**Explanation:**

First Part = x

[x * (0.06)*6] / (388800 – x)*0.05*2 = 5/4

1.44x = 19400 – 0.5x

x = 10000

Second Part = 38800 – 10000 = 28800**Harshita lent out some money at 6% Simple Interest per annum. After one year, Rs.6800 is repaid and the rest of the amount is repaid at 5% per annum. If the second year’s interest is 11/20 of the first year’s interest, find what amount of money was lent out.**

A. 18500

B. 10080

C. 17000

D. 18000

E. None of the Above

###### Answer & Explanation

**C. 17000**

**Explanation:**

P – amount lent by Harshita

I=.06*P —(i)

The interest for second year as X=(P+I-6800).05 —(ii)

x=(11/20)I —(iii)

Put (i) in (ii) and (iii)

P = 17,000**Vikram borrows a sum of Rs.1500 at the beginning of a year. After four months Rs.2100 more is borrowed at a rate of interest double the previous one. At the end of one year, the sum of interest on both the loans is Rs.416. What is the first rate of interest per annum?**

P = 2100

Rate of Interest = 2x

SI = 4200x/100 = 42x

57x = 416

x = 7.3%**Rahul invested a sum of money at Simple Interest at a certain rate of interest for three years. Had it been invested at a 4% higher rate, it would have fetched Rs.480 more. Find out the Principal amount that was invested by Rahul?**
