Alice in wonderland
Alice was bored that day,so she was sitting on the riverbank .Suddenly she notices a talking, White Rabbit with a pocket watch .It ran fast,and she followed it, down a rabbit hole .She fell into the hole and found a magical wonderland with dark trees, beautiful flowers.She found many ways numbered from 1,2,3,........18.she was confused which is the right way that will lead her to her home. She found a cute bird, standing in one of the tree. Alice asked the bird the way to go back to her home.The bird said a two digit number( say 23 ) and asked her to find the sum of its digits (2+3=5) and that numbered way will lead her to her home.Alice was already confused, so pls help Alice in finding the route to her home....

INTERCEPTS
INTERCEPTS
Emily is a very popular Maths Teacher in School. She retires from her service today. Her 7th class students like her very much and they wanted to give her a grand farewell at school. The school HeadMistress is a very strict person and she didn't give permission for them to conduct the farewell in the school premises. The students decided to conduct the farewell at Emily Mam's house itself.
They know the street in which Emily mam lives. The student leader asked Emily Mam to tell her house number. Emily Mam's last class was on Equation for a straight line. She said that a straight line can be represented by the equation y=mx+c and you know how to find the x-intercept and y-intercept of the line and my house number is the sum of the x-intercept and y-intercept of the line.
The students were puzzled. Can you help the students find the house number of Emily Mam?
