Answer:
hiii
your answer is here !
Step-by-step explanation:
=> Ratio of weights of B : A : C = 9×1 : 5×1 : 5×3 = 9 : 5 : 15
∴ 9x + 5x + 15x + 15 = 189
∴ x = 6,
=> Present weight of A = 5 × 6= 30kgs

Step-by-step explanation:
solve:-Answer
suppose,
That number of the mind is x
=> Ratio of weights of B : A : C = 9×1 : 5×1 : 5×3 = 9 : 5 : 15
then,
A:B:C=5x:9x:15x
put the present weight,
∴ 9x + 5x + 15x + 15 = 189
∴ x = 6,
=> Present weight of A = 5x
5× 6= 30kgs
=> B =9x= 9×6= 54kg
=>C =15x=15×6=90kg
