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...

Value increased d =140

Each student will get 7$back Put back the value of d in the options to get 7$
