Question about Computers & Internet

Mr Tan invested 35,000 and Mrs Tan invested 45,000

The equation to solve this is given by:

mr Tan's money x

Mrs Tan's money x + 10000

x times .05 + (x + 10000) times .05 = 4000

solve for x

While it's fairly easy to fit solar panels on your roof to generate electricity - and save money - investing in funds that hold the wind and solar firms offers more of a challenge.

It sounds like the perfect investment. Equip your house with solar panels and look forward to dramatically reduced utility bills and the potential to earn a handsome return by selling any excess energy to the electricity grid.

Thousands of people across the country have already embraced this idea since the government introduced the Feed-in Tariffs (FIT) Scheme in April 2010 to encourage the uptake of small-scale renewable and low-carbon technologies.

Greg Shreeve, the insight manager at the Energy Saving Trust, believes getting solar panels installed is a no- brainer for many people. The potential benefits to be enjoyed, he argues, more than makeup for the upfront costs.

"The technology pays for itself within 11 years and will go on generating electricity for your home," he says. "It's a great way to actually start making money when energy prices are rising. It's free electricity and low-carbon technology, so a winner all round."

There are 2 values for interest, say R and r, and R = 0.05, r = 0.04

There are 2 values for the amount earned, from the 2 banks, say I and i, and we know I + i = 100

There are 2 values for principal invested, say P and p, and we know P + p = 2125

There is only one value for period, say t = 1

So then I = P * 0.05 * 1 and

i = p * 0.04 * 1 and

I + i = 100 and

P + p = 2125

then

0.05P + 0.04p = 100

P + p = 2125

P = 2125 - p

0.05 ( 2125 - p) +0.04p = 100

106.25 - 0.05p + 0.04p = 100

106.25 - 0.01p = 100

0.01p = 6.25

p = 625

so

P = 2125 - 625 = 1500

so the amounts were $1500 and $625

A=P(1+i)^n, where P is the Principal, i is the interest rate per period, and n is the number of periods.

A=10,000(1+0.075)^3, assuming the interest is compounded annually

For 30 years, we would replace the number of period 3 with a 30.

Good luck,

Paul

Two ways to get to the same answer:

1) If X,Y, & Z are invested in the ratio of 4:5:6 then the amount invested in Z is 6/(4+5+6) times the total of N1200

= 6/15 * 1200

= N480

(Note: X is 4/15 and Y is 5/15 of the total investment,

4/15 + 5/15 + 6/15 = 15/15)

2) The second sentence says: Income from X plus income from Y minus income from Z is N140 and total income is N700. Total income is 700/1200 of the investment.

As formulas:

(Inc X + Inc Y) - Inc Z = 140 (rewriting: Inc X + Inc Y = 140 + Inc Z)

Inc X + Inc Y + Inc Z = 700

Substituting second formula into third:

(140 + Inc Z) + Inc Z = 700

140 + 2 Inc Z = 700

2Inc Z = 700 - 140 = 560

Inc Z = N280

Inc Z is also 700/1200 of investment in Z.

N280 = 700/1200 investment in Z

Investment in Z is 1200/700 * N280

Investment in Z is N480.

1) If X,Y, & Z are invested in the ratio of 4:5:6 then the amount invested in Z is 6/(4+5+6) times the total of N1200

= 6/15 * 1200

= N480

(Note: X is 4/15 and Y is 5/15 of the total investment,

4/15 + 5/15 + 6/15 = 15/15)

2) The second sentence says: Income from X plus income from Y minus income from Z is N140 and total income is N700. Total income is 700/1200 of the investment.

As formulas:

(Inc X + Inc Y) - Inc Z = 140 (rewriting: Inc X + Inc Y = 140 + Inc Z)

Inc X + Inc Y + Inc Z = 700

Substituting second formula into third:

(140 + Inc Z) + Inc Z = 700

140 + 2 Inc Z = 700

2Inc Z = 700 - 140 = 560

Inc Z = N280

Inc Z is also 700/1200 of investment in Z.

N280 = 700/1200 investment in Z

Investment in Z is 1200/700 * N280

Investment in Z is N480.

Following formula we can use.

S=P(1+RT)

WHERE S =INVEST AMOUNT+PROFIT

P=INVEST AMOUNT

R= RATE OF RETURN

T=TIME IN YEARS

EX : (300+x) = x(1+(5.4/100)*1)

(300+x)*100 = 105.4x

x=30000/5.4

x=5555. 4
