Question

A is 33.33% less than a+b and b+c is 41.66% more than c find a:b:c
​

Answer 1

solution - A is 33.33% less than A+B

A=(A+B)-33.33% of (A+B) = (A+B) -1/3 (A+B) -2(A+B) /3

A/A+B=2/3 , A+B/A=3/2 , A+B/A-1 = 3/2-1 , B/A=1/2

B=1

A=2

B+C is 43.75% of C = C+7/16

=23/16

B+C/C=23/16 , C=16 , B+C=23 , B+16=23 , B=7

A:B:C = 14 : 7 : 16

answer is 14 : 7 : 16
