Question

if √14+6√5 = a+√b then find b^2-a^2​

Answer 1

Step-by-step explanation:

Answer:

ln this question,

Principal amount (P) = Rs500.

Rate of interest (R) = 4% per year .

And

Time period (T) = 2years.

NOW,

Using formula to find interest using principal amount , time period and rate of interest.

We get,

\begin{lgathered}Interest (I)= \dfrac {PRT}{100} \\ \\ \dfrac {500 \times 4 \times 2}{100} \\\\ =Rs40\end{lgathered}

Interest(I)=

100

PRT

100

500×4×2

=Rs40

So,

Total amount to be returned after 2 years will be:-

P + I

= 500 + 40

= Rs540.

So,

Amount which is to be returned after 2 years will be Rs 540.
