a pie chart shows total marbles Raju has. if there are 121 yellow marbles ,how many blue marbles are there?
pie chart has 4 partitions. one partition shows 121 marbles, 2nd partition shows a right angle ,3rd partition shows red marbles as 1/6th & 4th partition shows 1/8th blue marbles.

SINCE FULL ANGLE =360

so 360 -(121+90)= 149

149 marbles= 1/8 + 1/6
i'm stuck !! PLEASE ENLIGHTEN!!

3/4 of marbles are yellow, red and blue.

Assume there are N marbles.

Then

121/N *360 + 1/6*360 + 1/8 * 360 = 3/4 * 360

121/N = (36 -14)/48 = 11/24

N = 24 * 11
.... finish it
