6.

What would be the compound interest accrued on an amount of 5000 Rs. at the end of 2 years at the rate of 16 % per annum?

**Answer: Option 'A'**

**Given **

principal = 5000

No. of years = 2

Rate of interest = 16

**Amount = P x (1+r/100) ^{n}**

we get Amount = 5000 x (1+16/100)

= 5000 x (116 / 100)

= 5000 x (116 / 100 ) x (116 / 100)

= 58 x 116

Compound interest = Amount - Principal

= 6728 - 5000

Akarsh left a will of Rs. 16,400 for his two sons whose age are 17 and 18 years.They must get equal amounts when they are 20 years at 5% compound interest. Find the present share of the younger son.

**Answer: Option 'B'**

**Given, total amount (to be shared by two sons at the age of 20 on Compound interest) = Rs. 16,400
Let the Present share (Principal amount) for 17 year old son = "X"
Then the Present share (Principal amount) for 18 year old son = (16,400 - X)
To attain 20 years of age,
=> 17 year old son takes 3 years (N = 3 years on Compound interest)
=> 18 year old son takes 2 years (N = 2 years on Compound interest)
Given, Rate of interest (R) = 5%
Given that, at the age of 20, two sons get equal amount
=> Compound Amount of 17 year old son = Compound Amount of 18 year old son
W.K.T, Formula for Compound Amount = P [1 + (R/100)]^{N}
=> X (1 + 5/100)^{3} = (16,400 - X) (1 + 5/100)^{2}
=> X (1 + 5/100) = (16,400 - X)
=> (105/100) X = (16,400 - X)
=> [(105/100) X] + X = 16,400
=> 205 X = 16,400 × 100
=> X = 16,40,000 / 205
=> X = 8,000
Therefore, Present share for 17 year old son = Rs. 8,000**

Find the simple interest on Rs. 1300 at 10 % per annum for 5 years

**Answer: Option 'A'**

**Given**

Principal : 1300

Rate of interest : 10

Number of years : 5

**Simple Interest = pnr / 100**

Simple Interest = (1300 x 5 x 10) / 100

= 13 x 5 x 10

= 650

So,**Simple Interest = 650**
