Answer:
There are 14 marbles in the box at first.
Step-by-step explanation:
Let the number of marbles in each box be X marbles.
Total number of marbles in 7 boxes = 7x
No. of Marbles taken away = 6 × 7 = 42
Total number of marbles left = 7x – 42
No. of marbles in 4 boxes = 4x
Now,
7x – 42 = 4x
=> 7x – 4x = 42
=> 3x = 42
=> x = 42/3
=> x = 14
Thus, there are 14 marbles in the box at first.
