A student went to take tuition from a Maths tutor. He went 90 m to the east from his home and then turned right. He then went 20 m and again turned right and went to a friend's house which is 30 m from that point. From his friend's house, he went 100 m towards north to reach his tutor's home. How far is his tutor's home from his home?

Jayesh starts from point A and drives 6 km towards south. He then takes a left turn and drives 3 km. He then takes a right turn and drives 2 km to reach a point B. Tania starts from point X, which is 5 km east of point A, and drives 8 km towards north. She then takes a left turn and drives 5 km to reach a point Y. What is the shortest distance between point Y and point A? (All turns are 90° turns only.)
