Question : If $4^{(x+y)} = 256$ and $(256)^{(x–y)} = 4$, what are the values of $x$ and $y?$
Option 1: $\frac{17}{8}$ and $\frac{15}{8}$
Option 2: $\frac{17}{4}$ and $\frac{15}{4}$
Option 3: $\frac{9}{17}$ and $\frac{15}{17}$
Option 4: $\frac{8}{17}$ and $\frac{8}{15}$
Correct Answer: $\frac{17}{8}$ and $\frac{15}{8}$
Solution : Given: $4^{(x+y)}=256$ ⇒ $4^{(x+y)} = 4^4$ ⇒ $x+y = 4$ ⇒ $x = 4-y$-----(1) And $(256)^{(x-y)}=4$ ⇒ $(4^4)^{(x-y)}=4^1$ ⇒ $4x-4y =1$-----(2) Putting the value of $x$ from equation (1), we get, $4(4-y)-4y = 1$ ⇒ $16-4y-4y =1$ $\therefore y =\frac{15}{8}$ Now, substituting the
Question : On simple interest, a sum of Rs. 640 becomes Rs. 832 in 2 years. What will Rs. 860 become in 4 years at the same rate of interest?
