Answer:
(a) 22 (b) 24 (c) 26 (d) 28 (e) 30 ( asked in CAT )Solution :-Here , A + B + C + D + E = 150A = B - 3A + C = 2ED + 5 = EB + D = A + C = 2 E2 E + 2 E + E = 150, E = 30D + 5 = 30 , D = 25B + 25 = 2 × 30 B = 35A = 35 - 3 = 3232 + C = 2 × 30 C = 28 option ( d ) is correctInequalityAbsolute ValueThe absolute value of a number measures its distance to the origin on the real number line.Since 5 is at 5 units distance from the origin 0, the absolute value of 5 is 5, |5|=5. Since -5is also at a distance of 5 units from the origin, the absolute value of -5 is 5, |-5|=5InequalityWe are ready for our first inequality. Find the set of solutions for |x|<5.Translate into English: we are looking for those real numbersxwhose distance from theorigin is less than 5 units. Obviously we are talking about the interval (-5,5): so all thevalues of X are -4 , -3 , -2 , -1 , 0 , 1, 2 , 3 , 4 . For the equation |x| ≤ 5, the solution willinclude 5 & -5 with the set of other numbers.Solving linear inequalities is very similar to solving linear equations, except for one detail:you flip the inequality sign whenever you multiply or divide the inequality by a negative.The easiest way to show this is with some examplesX + 3 < 2 add -3 to both the site- 3 -3-------------------
