If 2 times the sum of two consecutive even numbers is greaten than 94, what is the smallest possibel value of the larger number. 2.A company has two factories A and B. Factory A has 62 workers and factory B has 40 workers. The manager of the company is going to employ a total of 39 more new workers. The new workers will be appointed to the two factories in the way that the total number of workers in factory A is not more than twice the total number of workers in factory B. How many new workers can be appointed to factory A at most?
1. If 2 times the sum of two consecutive even numbers is greater than 94, what is thesmallest possible value of the larger number. Solution : Let n be the larger number. Then, the smaller number = n - 2 The sum of the two numbers is greater than 94 : 2 * [n + (n - 2)] > 94 4n - 4 > 94 4n > 98 n > 24.5 Since n is an even number, then the smallest possible value of the larger number = 26 2. A company has two factories A and B. Factory A has 62 workers andfactory B has 40 workers. The manager of the company is going to employ a total of 39 more newworkers. The new workers will be appointed to the two factories in the way thatthe total number of workers in factory A is not more than twice the totalnumber of workers in factory B. How many new workers can be appointed tofactory A at most? Solution : Let n be the number of new workers appointed to factory A. Then, the number of new workers appointed to factory B = 39 - n 62 + n ≤ 2[40 + (39 - n) 62 + n ≤ 158 - 2n 3n ≤ 96 n ≤ 32 Number of new workers can be appointed to factory at most = 32
