d becomes 1.4d after increase in stock value.

1.4d has to be divided equally among 20 people.

=1.4d/20. =7d/100

Hi azamaka,

This question can be solved by TESTing VALUES.

We're told that each of 20 members donated the SAME amount of money to a fund and that the TOTAL was D dollars.

IF...
each member contributed $1, then D=20, and we have$20 worth of stock

Next, we're told that the value of the stock increased 40%...

$20 + (.4)($20) = $20 +$8 = $28 The stock is then sold and the money is given equally to the 20 members. This means that each member received...$28/20 = $1.40 We're asked for how much each member received, so we're looking for an answer that equals 1.4 when D=20... There's only one answer that matches...

There are 20 people with each contributing an equal amount, say 'x'

Given, 20x = d
after the stock value increases by 40%, 20x is equivalent to 1.4d

20x=1.4d
x=1.4d/20
x=7d/100

option E

(A) 800d

(B) $$7d/5$$

(C) $$d /20 + 40$$

(D) $$d/2$$

(E) $$7d/100$$

After the stock increased by 40%, the new value was 1.4d.

Thus, each of the 20 members received 1.4d/20 = 14d/200 = 7d/100.

If 20 students each gave 5 $, then d = 100 Value increased d =140 Each student will get 7$ back

Put back the value of d in the options to get 7\$
