Find the compound interest on Rs. 2000 for one year at the rate of '20%' per annum. If theinterest compounded quarterly.​
trasher [3.6K]

Given:

Principal = Rs. 2000

Rate of interest = 20% p.a. compounded quarterly.

Time = 1 year

To find:

The compound interest.

Solution:

Formula for amount:

A=P\left (1+\dfrac{r}{n}\right)^{nt}

where,

P = Principal

r = Rate of interest

t= Time

n = number of times interest compounded in an year.

Putting P=2000, r=0.2, n=4 and t=1, we get

A=2000\left (1+\dfrac{0.2}{4}\right)^{4(1)}

A=2000\left (1.05\right)^{4}

A=2000\left (1.21550625\right)

A=2431.0125

Now, the compound interest is

C.I.=A-P

C.I.=2431.0125-2000

C.I.=431.0125

Therefore, the compound interest is Rs 431.0125.

Exterior angles of a triangle. Please help. Due today
yulyashka [42]

Answer:

1) 140 2)68 3) 125 4) 140

Step-by-step explanation:

for these, because you're trying to find the angle from 180 degrees, you would subtract the angle on the 180 degree line from 180.

1) 180-40 = 140

2) 180-112 = 68

3) 180-55 = 125

4) 180-40 = 140

Hope this helps!
