Question

nine person were to pay equal amount to a certain fund. if there were 3 persons less , then each would have to contribute four ruppes more . what is the amount of the fund .
want full explanation ​

Answer 1

Step-by-step explanation:

9 persons paid - 9x rupees

6 persons paid - 6x rupees

if y = x+4

then 6y = 6 (x+4)

9x = 6 (x+4)

9x = 6x + 24

9x-6x = 24

therefore,

x = 24/3

x = 8

Fund = 9x = 9 ✖ 8 = 72 rupees
