Answer:

= 4

Step-by-step explanation:

Combine like terms

11x−7x=16

4 = 1 6

Divide both sides of the equation by the same term

4 = 1 6

4 / 4  =  1 6/ 4

44x​=416​

3

Simplify

1)Cancel terms that are in both the numerator and denominator

2)Divide the numbers

= 4

Solution

= 4

In how many year the interest will became equal to the principal is rs.1200 is deposited at the rate of 25% in a bank ​
mrs_skeptik [129]

Given:

Principal = Rs. 1200

Rate of interest = 25%

To find:

The time in which the interest will became equal to the principal.

Solution:

We have,

P=1200

r=\dfrac{25}{100}

r=0.25

If interest is equal to the principal, then

Amount=Principal+Interest

Amount=1200+1200

Amount=2400

The formula for amount is:

A=P\left(1+r)^n

Substituting A=2400, P=1200, r=0.25 in the above formula, we get

2400=1200(1+0.25)^n

\dfrac{2400}{1200}=(1.25)^n

2=(1.25)^n

Taking log on both sides, we get

\log2=\log(1.25)^n

\log2=n\log(1.25)               [\because \log a^b=b\log a]

\dfrac{\log2}{\log(1.25)}=n

n\approx 3.11

Therefore, the interest will became equal to the principal in about 3.11 years.
