**At what percent per annum will be SI on sum of money is equal to 3/5 of the amount in 5 years.**

a) 10%

b) 20%

c) 30%

d) 40%

Answer –**c) 30%**

R =30

**Priya borrows 1000 rupees at the rate of 11% per annum on SI and rahul borrows 780 rupees at the rate of 15% per annum on SI. In how many years will the amount of debt of priya and rahul be equal.**

**A sum of 8000 rupees is divided between two people A and B at the rate of interest of 4% and 5% respectively. The total interest earned after 2 years is equal to 750. Then find the ratio of investment between A and B.**

a) 3:11

b) 5:11

c) 6:11

d) 7:11

Answer –**b) 5:11**

**Solution:**

Let A get X rupees and B get 8000-X rupees.

750 = X*(4/100)*2 + (8000-X)*(5/100)*2

X =2500 and 8000-2500 = 5500

Ratio 5:11

**A part of 2000 is lent at 6% per annum and rest sum is lent at 8% per annum. If total interest earned after 4 years is 500. Then the sum lent at 8%**.

a) 250

b) 350

c) 450

d) 550

Answer –**a) 250**

Solution:

Let sum lent at 8% is X

500 = X*(8/100)*4 + (2000-X)*(6/100)*4

**Sohan invested 20000 rupee in fixed deposit at the rate of 10% simple interest. After every 3 rd year he added interest to principal. Find the interest earned at the end of 6**^{th}year.

For the first 3 years SI will be = 20000*10/100*3 = 6000

Now he add 3000 to the principal i.e = 20000+6000 = 26000

Now interest earned at end of 6^{th}year = 26000*10/100*3 = 7800

**A statue of 550BC is priced at 15000 rupees. But a person wants instalment on the statue. So he gaves 10000 rupee cash and make an instalment of rupees 650 for 8 months. Find the rate of interest charged by the shopkeeper.**

c) 8%

d) 10%

Answer –**b) 6%**

**Solution:**

Total amount buyer pays = 10000 + 650*8 = 15200

So to find the interest rate, 200 = 5000*(8/12)*R/100

So r= 6%.

**Rs. 12000 was invested for 2 years, partly in scheme A at the rate of 5% SI per annum and partly in scheme B at the rate of 8% SI per annum. The total interest received at the end was Rs.1800. What amount of money was invested in scheme A ?**

a) 2000

b) 1600

c) 3200

d) 4200

Answer –**a) 2000**

**Solution:**

x *5*2/100 + (12000-x)*2*8/100 = 1800

x/10 + 192000-16x/100 = 1800

10x+192000-16x=180000

6x = 12,000

X=2000
