In what time a certain sum of money will be 2.5 times at 10% rate of interest

Mathematics
1 answer:
WITCHER [35]3 years ago
5 0

Answer:

Step-by-step explanation:

It takes 15 years to get 2.5 times the sum at 10% p.a.

Let the principal be 'P'.

Let the amount be '2.5P'

Rate = 10%

Amount = Principal - Interest

2.5 P = P - Interest

Interest = 1.5 P

So, we get that

1.5P =\frac{P*R*T}{100} \\1.5 * 100 = 10 * T\\T = 15 years

hope it helps :)

What 3 consecutive integers equal 84
Murrr4er [49]

First represent your 3 consecutive integers as follows.

X ⇒ <em>first integer</em>

X + 1 ⇒ <em>second integer</em>

X + 2 ⇒ <em>third integer</em>

<em />

Since their sum is 84, our equation reads x + (x + 1) + (x + 2) = 84.

Simplifying on the left side we get 3x + 3 = 84.

Now subtract 3 from both sides to get 3x = 81.

Dividing both sides by 3, we find that <em>x = 27</em>.

Finally, make sure you list all your answers.

If <em>x </em>is 27 then <em>x </em>+ 1 is 28 and <em>x </em>+ 2 is 29.

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

7(2x - 5) = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 7:                   2x - 5 = 3
  2. Isolate <em>x</em> term:                2x = 8
  3. Isolate <em>x</em>:                         x = 4

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                  7(2(4) - 5) = 21
  2. Multiply:                             7(8 - 5) = 21
  3. Subtract:                            7(3) = 21
  4. Multiply:                             21 = 21

Here we see that 21 does indeed equal 21.

∴ x = 4 is the solution to the equation.
