The interest for 3 years on Rs 2400 is Rs 576. find the interest on Rs 4000 for 2 years at the same rate of interest give me correct answer or explaination​ with solution stepby step

➤ Answer :-

First of all, we should calculate the rate of interest to the first problem.

The next step is to calculate the simple intrest with obtained answer to first problem.

━━━━━━━━━━━━━━━

➤ Given :-

Simple Interest :- ₹ 576

Principle :- ₹ 2400

Time :- 3 years

➤ To Find :-

Rate of interest to the first problem in the following question

➤ Formula required :-

➤ Solution :-

Here,

SI = Simple Interest

P = Principle

T = Time

So,

The rate of interest is 8 .

━━━━━━━━━━━━━━━

Now, we can find the solution to the second problem

➤ Given :-

Principle :- ₹ 4200

Time :- 2 years

Rate of interest :- 8  

➤ To Find :-

Simple interest for the second problem of the question

➤ Formula required :-

➤ Solution :-

The simple interest for the second problem is ₹ 672

Step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
