Given:
Principal = Rs. 2000
Rate of interest = 20% p.a. compounded quarterly.
Time = 1 year
To find:
The compound interest.
Solution:
Formula for amount:
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
Now, the compound interest is
Therefore, the compound interest is Rs 431.0125.
The value of the expression will be equal to 145.
<h3>What is an expression?</h3>
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that make an expression for divide 50 by half and add 20 and multiply by 2.
The expression will be solved as below,
E = 50/2 + 25 x 2 + 50 + 20
Solve the above expression by PEMDAS,
E = 25 + 50 + 70
E = 145
