Question

what is the factor of (x+y)-(x^5+y^3)?​

Answer 1

Step-by-step explanation:

2500 into two parts such that if one part is lent at 3% for 2 years and the other at 4% for two years, then the total income is 160.

Let first part be x and second part be 2500 - x.

Case :- 1

Principal, P = x

Rate of interest, r = 3 %

Time, n = 2 years

We know,

Simple interest ( SI ) received on certain sum of money of P invested at the rate of r % per annum for n years is given by

\begin{gathered}\boxed{\rm{  \: \: SI \: = \: \frac{P \times r \times n}{100} \: \: }} \\ \end{gathered} SI=100P×r×n

So, on substituting the values, we get

\begin{gathered}\rm \: SI_1 \: = \: \dfrac{x \times 3 \times 2}{100} \\ \end{gathered}SI1=100x×3×2

\begin{gathered}\rm\implies \:\rm \: SI_1 \: = \: \dfrac{6x}{100} - - - (1) \\ \end{gathered}
