1 small clarification puys..
Mr. Sam has a wife and three children. Mrs. Sam is three years younger to Mr. Sam. The ages of the three children, being in AP, add up to 6/5 times that of Mr. Sam's age. While the youngest child of Mr. Sam is a female, the sum of the ages of the three males in the family is 85 years. The age of the second son of Mr. Sam can be:
So the 3 children's are a-d,a,a+d. In the question it is given as SECOND SON. So now will it be a or a+d??
How to interpret this one? 1st daughter, 2nd son and 3rd son? Or Daughter, 1st son and 2nd son? 👼👼

7 different objects must be divided into three people. In how many ways this can be done if one or two of them must get no object.
My approach :
7 distinct object should be given to 3 distinct people.
Condition : either one or two person must not bet any object, that means
7 object should be given to two of them OR 7 object should be given to one of them
1st: two persons selected in 7C2 and distributed in 2^7 ways i.e. 7C2*2^7
2nd: only one should be given all 7 object, that one person selected in 7C1 ways and only one way to distribute = 7C1*1
i.e. 7C2*2^7 + 7

A teacher asks one of her students to divide a 30-digit number by 11. The number consists of six consecutive 1's, then six consecutive 2's, and likewise six 3's, six 4's and six 7's in that order from left to right. The student inserts a three-digit number between the last 4 and the first 7 by mistake and finds the resulting number to be divisible by 11. Find the number of possible values of the three-digit number.
