A flexible tube called an endoscope is used to view different parts of the digestive tract. When passed through the mouth (as shown on the left), an endoscope can be used to examine the esophagus, stomach, and some of the small intestine.

(C) Bulimia

Bulimia nervosa is an eating disorder characterized by binge eating, which involves consuming large amounts of food in a short period of time, often with a lack of control. Individuals with bulimia then engage in compensatory behaviors, such as vomiting, excessive exercise, or fasting, to prevent weight gain. The person described in the question, who does not know when to stop eating, may be exhibiting characteristics of binge eating, which is a key feature of bulimia. Diabetes, anorexia, and hyperacidity are different health conditions and not typically associated with an inability to stop eating in the described manner.

1. Answer : 4 Explanation : Required ratio = 10+2+510+15+10=1735≈12=1:2    2. Answer : 1 Explanation :  A to B Speed =140×35  = 84   B to C Speed = 91×34 = 68.25  C to D Speed = 149×60103 = 86.796   D to E Speed = 88×34 = 66   E to F Speed =  106×45= 84.8   F to G Speed = 1762 = 88   G to h Speed =  110×45= 88   Average speed of entire trip = 84+68.25+86.796+66+84.8+88+887 =80.83    3. Answer : 3  Explanation :  Total half time = 10 + 2 + 5 + 10 + 15 + 10 = 52  Total half time, if the train stops at each city for 50% more=52×150100=78  Train will arrive at city H after departing from city A = 18.25 + (78 - 52 )=18.25 + 26=18.51   4. Answer : 2   Explanation : Average speed = 84+68.25+86.796+66+84.8+88+887=80.83=81 km/hr   5. Answer : 1  Explanation :  Required percentage of time = 1.40+1.20+1.43+1.20+1.15+2+1.1518.25-7×100= 10.2311.25×100 = 91.8 %
