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

hence, each member receives 7d/100
option E

A group of 20 friends formed an investment club, with each member contributing an equal amount to the general fund, which amounted to d dollars, in Stock X. The value of the stock subsequently increased 40 percent, at which point the stock was sold and the proceeds divided evenly amoung the members. In terms of d, how much money did each member of the club receive from the sale?


(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.

Answer: E

(E) \(7d/100\)

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$
