Question

3/7 of the marbles in a box are red. If the number of blue marbles more than the red marbles by 52, how many blue marbles are there in the box?

Answer 1

Answer:

364

Step-by-step explanation:

let's take the total no. of marbles as x

3/7x(no. of red marbles) + 52 = blue marbles

Therefore, 52 + 3/7 x + 3/7x = 6/7x + 52 = x

52 = x - 6/7 x = 1/7 x

x= 52 * 7 = 364
