Answer:

The answer to your question is x = 2

Step-by-step explanation:

Process

1.- Use proportions to solve this problem

$\frac{4x + 2}{23} = \frac{2x + 16}{23 + 23}$

2.- Solve for x

46(4x + 2) = 23(2x + 16)

Expand

184x + 92 = 46x + 368

Simplify

184x - 46x = 368 - 92

138x = 276

x = 276/138

Result

x = 2

Answer:

Future requirement of water = 115,517 mega-liters

Step-by-step explanation:

Given:

Current requirement of water (C) = 48,000 mega-liters

Increasing rate per year (g) = 5% = 0.05

Number of year (n) = 18 years

Find:

Future requirement of water = ?

Computation:

$Future\ requirement\ of\ water = C(1+g)^n\\\\Future\ requirement\ of\ water = 48,000(1+0.05)^{18}\\\\ Future\ requirement\ of\ water = 48,000(1.05)^{18}\\\\ Future\ requirement\ of\ water = 48,000(2.4)\\\\Future\ requirement\ of\ water = 115,517 (Approx)$
