Question

In a bag of small balls 1/4 are green , 1/8 are blue, 1/12 are yellow and the remaining 26 white. How many balls are blue?

Answer 1

3 balls of blue if u tke the L.C.M of the three numbers

Answer 2

let x be no. of balls in bag
therefore
no. of green balls=$\frac{x}{4}$
no. of blue balls=$\frac{x}{8}$
no. of yellow balls=$\frac{x}{12}$
no. of white balls=$26$
$\frac{x}{4}+ \frac{x}{8}+ \frac{x}{12}+26=x$
lcm of 4 ,8 and 12 is 24
$\frac{6x+3x+2x}{24} +26=x$
$\frac{11x}{24}+26=x$
$26= \frac{24x-11x}{24}= \frac{13x}{24}$
$x=48$
total no. of balls is 48
total no.of blue are 48/8=6
