360 sweet boxes are distributed among A, B and C. If the ratio of the number of sweet boxes distributed by A and C

360 sweet boxes are distributed among A, B and C. If the ratio of the number of sweet boxes distributed by A and C is 12:11 respectively and the number of sweet boxes distributed by B is 8.33% more than that of A, then find the difference between the number of sweet boxes distributed between B and C?

a)            20

b)            50

c)            80

d)            70

e)            None of these

sol:

Le the number of sweet boxes distributed by

A=12x

And the number of sweet boxes distributed by

C=11x

The number of sweet boxes distributed of

B=12x*13/12=13x

Required difference=360*(13x[1]11x)/36x=360*2/36=20
