**Out of Rs. 60,000 that Rahul has, he lends Rs. 10,000 at 11/2 % per annum simple interest and Rs. 32,000 at 6% per annum simple interest. He lends the remaining money at a certain rate of interest so that he gets total annual interest of Rs. 4000. The rate of interest per annum, at which the remaining money is lent, is?**

A.5%

B.7.5%

C.8%

D.8.5%

E.10%

###### Answer & Explanation

Answer –**D.8.5%**

**Explanation :**

Total Amount = 60000

Amount divided into three parts – x, y, z

x = 10000, T = 1 yr

SI(x) = (10000 * 11/2)/100 = 550

y = 32000 R = 6%

SI(y) = (32000 * 6)/100 = 1920

Total Interest = 4000, Interest on the remaining amount = 4000 – 550 – 1920 = 1530

z = 60000 – 32000 – 10000 = 18000

R = (1530 * 100) /18000 = 8.5%

**Vivek invests Rs 15000 as fixed deposit at a bank at the rate of 10% per annum SI. But due to some pressing needs he has to withdraw the entire money after 5 years, for which the bank allowed him a lower rate of interest. If he gets Rs 8250 less than what he would have got at the end of 10 years, the rate of interest allowed by the bank is**

A.8%

B.8.5%

C.9%

D.9.5%

E.10%

###### Answer & Explanation

Answer –**C.9%**

**Explanation :**

P=15000, T1=10 years, T2=5 years, R1=10%, R2=?

[(15000*10*10)/100 – (15000*R2*5)/100] = 8250

15000 – 750R2 = 8250

R2 =**9%**

**A father left a will of Rs.55 lakhs between his two sons aged 8.5 and 16 such that they may get equal amounts when each of them reach the age of 21 years. The original amount of Rs.55 lakhs has been instructed to be invested at 10% p.a. SI. How much did the elder son get at the time of the will?**

A.25 lakh

B.26 lakh

C.28 lakh

D.33 lakh

E.36 lakh

###### Answer & Explanation

Answer –**D.33 lakh**

**Explanation :**

Let x be the amount of elder son at the time of will & Younger son’s amount at the time of will (550000 -x)

For elder son, T= 21-16=5

For younger son, T=21-8.5= 12.5

Amount Should be equal so,

x + [(x*10*5)/100] = (5500000-x) + [((5500000-x)*10*12.5)/100]

3x/2 = 12375000 – 2.25x

**x=3300000**

**Manish borrows 8000 at simple interest from a money lender. At the end of 3 years, he again borrows 7000 and closes his account after paying 8415 as interest after 8 years from the time he made the first borrowing. Find the rate of interest.**

A.6%

B.6.5%

C.8%

D.8.5%

E.9%

###### Answer & Explanation

Answer –**D.8.5%**

**Explanation :**

Let x be the rate of interest

8000*3x/100 + 15000*5x/100 = 8415

240x + 750x = 8415

X = 8.5

**A portion of Rs.8500 is invested at a8% per annum, while the remainder is invested at a 3% per annum. If the annual income from the portion earning a 8% per annum is thrice that of the other portion, what is the total income from the two investments after one year?**

A.Rs.350

B.Rs.370

C.Rs.450

D.Rs.480

E.Rs.520

###### Answer & Explanation

Answer –**D.Rs.480**

**Explanation :**

8x + 3y = z (Total Income)

x + y = 8500 -(1)

8x= 3(3y)

8x – 9y = 0 -(2)

By solving (1) and (2) we get, x = 4500 so y = 4000

(4500*8*1)/100 + (4000*3*1)/100 = 360 + 120 = 480

**Raghu lends Rs 50,000 of two of his friends. He gives Rs 30,000 to the first at 6% p.a. simple interest. He wants to make a profit of 10% on the whole. The simple interest rate at which he should lend the remaining sum of money to the second friend is**

A.8%

B.16%

C.11%

D.17%

E.19%

###### Answer & Explanation

Answer –**B.16%**

**Explanation :**

S.I. on Rs 30000

=(30000×6×1)/100 = Rs. 1800

Profit to made on Rs 50000

= 50000×10/100=Rs 5000

S.I.on Rs.20000 = 5000-1800 = Rs.3200

Rate=(S.I.* 100)/(P * T)=(3200×100)/20000

=16% per annum

P1:P2 = 7:5
