Let the number of coins be - N

Then, N - 1 is a multiple of 1, 2, 3, 4, 5, 6 but not 7. The LCM of 1, 2, 3, 4, 5, 6 is 60
Again N is a multiple of 7.
So, N should be any number which is a multiple of 7 and N - 1 is a multiple of 60. So upon finding the multiples of 60 and adding 1 to them we find 60 * 5 = 300 + 1 = 301 is such a number.

Therefore N = 301.

The solution has to be a multiple of 7 because the seven robbers have to divide the coins equally.
I have tried multiples of 7 until I reached 301 which complies allow the robbers to divide the coins equally.
The answer is 301 coins

On the market, Mrs. Jain and Mrs. Sharma sell apples. Mrs. Jain sells her apples per two for Rs 50. The apples of Mrs. Sharma are a bit smaller; she sells hers per three for Rs 50. At a certain moment, when both women have the same amount of apples left, Mrs. Sharma is being called away. She asks her neighbor to take care of her goods. To make everything not too complicated, Mrs. Jain puts all apples to one big pile, and starts selling them for Rs 100 per five apples. When Mrs. Sharma returns at the end of the day, all apples have been sold. However, when they start dividing the money, there appears to be a shortage of Rs 350.

Supposing they divide the amount of money equally, how much does Mrs. Jain lose with this deal?
