Question

ok, I need help on this P6 problem. No simultaneous equations pls. :)

There are several red balls and white balls on the table.
If 1 red ball and 1 white ball are removed together each time until no red balls are left on the table, then the number of remaining white balls is 50.
if 1 red ball and 3 white balls are removed together each time until no white balls are left on the table, then the number of remaining red balls is also 50.
Find the total number of red balls and white balls at first.

Many thanks in advance!

Hi heutistmeintag,

Referring to Model representing White Balls:
1 Part + 50 in 1st scenario = 3 units in 2nd scenario
because it says for every 3 white balls & 1 red ball are removed each time till no white ball left. Therefore all of the white balls are divided into 3 units.
From the 2 models, 1 Part = 2 units and 50 = 1 unit

Referring to Model representing Red Balls:
(1 unit = 50) is confirmed in 2nd scenario.
1 unit of Red Balls is removed and left with 50.
(Remember 1 Part = 2 units?)

Hope this can help you.
