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

Using fixed simple interest:

start with $1,500. Every year you get $75 in interest.

so after 3 years you have $1,500 + $225 = $1,725.00

Compound interest:

If you use/want compound interest you gain 5% of the new amount every year. So start with $1,500

Year 1: $1,500 + $75 = $1,575

Year 2: $1,575 + $78.75 = $1,653.75

Year 3: $1,653.75 + $82.6875 = $1736.4375

So final sum is $1736.4375.

However banks usually round down so $1736.43

- Let, the maximum amount that is to be given is "x". Then, next student will receive an amount of "x-40", the next one "x-80", the next one "x-120", the next one "x-160", the next one "x-200" and the least amount will be "x-240"...... as this amount was to be distributed among 7 students.

- So according to the given condition, the money balance gives........ x+(x-40)+(x-80)+(x-120)+(x-160)+(x-200)+(x-240) = 1400

=> 7x = 2240

=> x = 320

Therefore, the distribution of the money will be 320, 280, 240, 200, 160, 120 and 80.

Guessing your non-phone question that SI is simple interest, the answer is just under 20%. Compounding makes the difference as it would double in 4 years at 20%. My trusty HP is in the van, so I'm guessing about 16%.

=10000*(1+0.96)^12

=10000*(1+0.10)^18

=10000*(1+0.10)^24

=10000*(1+0.10)^18

=10000*(1+0.10)^24

The present value of any future monthly (?) stream of payments stretching some 24 years into the future takes into account the time value of money and depends on the interest rate assumed to apply for each month throughout those 24 years.

There are formulae to calc this for an equal monthly payment and a constant interest rate, over the term but for a variable interest rate you need a spreadsheet.

In the simple case of zero interest assumed throughout the term, present value = current principal balance, but for any positive interest rate, the total present value of the future payment stream is less than the current principal balance.
