Class XI Identify the solution set for –( x – 3 ) + 5 – 2x (−∞,−1) (−∞,−2) (−∞,−5) none of these A man wants to cut three lengths from a single piece of board of length 91 cm. The second length is to be 3 cm longer than the shortest and third length is to be twice as long as the shortest. What are the possible lengths for the shortest board if t 3 ≤ × ≤ 5 3 ≤ × ≤ 91 5 ≤ × ≤ 91 8 ≤ × ≤ 22 In the first four papers each of 100 marks , Rishi got 95 , 72 , 83 marks . If he wants an average of greater than or equal to 75 marks and less than 80 marks , find the range of marks he should score in the fifth paper . 52 < × < 77 25 < × < 75 75 < × < 80 73 < × < 100 The marks scored by Rohit in two tests were 65 and 70. Find the minimum marks he should score in the third test to have an average of atleast 65 marks. 60 75 65 70 Identify solution set for [| 4 −− x | + 1 < 3| 4 x | 1 3?
