Answer:
Hey mate here is your answer.//
Step-by-step explanation:
In a bag of balls, 1/4th are green, 1/8th are blue, 1/12th are yellow and the remaining 26 are white. How many balls are blue?
There are 4 colours of balls - green, blue, yellow and white.
Add (1/4)+(1/8)+(1/12) = (6/24)+(3/24)+(2/24) = 11/24 so the balance or (24–11)/24 = 13/24 = 26 white. Hence the total number of balls are 2*24 = 48.
Of the 48 balls, green are (1/4)*48 = 12, blue are (1/8)*48 = 6, yellow are (1/12)*48 = 4 and the rest, white are 26.
Check: Total number of balls = 12+6+4+26 = 48
Answer: 6 balls are blue.

Correct Question
In a bag full of small balls; 1/4 of these balls are green 1/8 are blue 1/12 are yellow and remaining white are 26. How many are blue?
Answer
Number of blue balls = 6
Explanation-
Let us assume that there are x balls in the bag.
A bag full of small balls, in which 1/4 of the balls are green.
Number of green of balls = x/4
Similarly, there are 1/8 blue balls and 1/12 yellow balls in the bag.
Number of blue balls = x/8
Number of yellow balls = x/12
Now,
Number of balls = Number of green balls + Number of blue balls + Number of yellow balls
⇒ x/4 + x/8 + x/12
⇒ (6x + 3x + 2x)/24
⇒ 11x/24
Also given in question that, remaining balls in the bag are white; which are 26.
Substitute the known values
⇒ x = 11x/24 + 26
⇒ x - 11x/24 = 26
⇒ (24x - 11x)/24 = 26
⇒ 13x/24 = 26
⇒ x/24 = 26/13
⇒ x/24 = 2
⇒ x = 48
Therefore,
There are total 48 balls in the bag.
But we have to find the number of blue balls.
So, Number of blue balls in the bag = 48/8
⇒ Number of blue balls = 6
