Consider the following statements: 1. The delay time is the time required to reach 50% of the final value in the first time. 2. The rise time is the time required for the response to rise from 10% to 90% of its final value for underdamped systems. 3. The rise time is the time required for the response to rise from 0 to 100% for the underdamped systems. Which of these statements are correct?
The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: Individuals with APD do not recognise subtle differences between sounds in words, even when the sounds are loud and clear enough to be heard.  Q: Central Auditory Processing Disorder, this is a condition that adversely affects how sound that travels unimpeded through the ear is processed or interpreted by the brain. R: They can also find it difficult to tell where sounds are coming from, to make sense of the order of sounds, or to block out background noises. S: People with APD may process thoughts and ideas slowly and have difficulty explaining them. It is important to realize that learning disabilities can affect an individual’s life beyond academics
A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?
