Answer:
119. The number has to be evenly divisible by seven for there to be no extras when counting in sevens, and it has to be odd in order for there to be one extra when counting by twos. It also can’t be evenly divisible by three through six. 119 is the first odd multiple of 7 that satisfies the requirements.

Answer:
There were 119 mangoes in the basket.
Step-by-step explanation:
X = 7n.
But x isn't divisible by 2,3,4,5,6.
So it must be divided by either 7 or other prime number.
Here, u get a clue as u multiply... As it leaves 4 when divided by 5, the last digit must be 9.
So, multiply with the prime having 7 as one's digit.
49 does not satisfy the condition.
If n = 17, x = 119. It satisfies the conditions.
So, it is 119
