If 5 pieces of wood had the avg length of 124 cm and median 140 cm . what is max. possible length of shortest wood?
1. 90
2. 100
3. 110
4. 140
5. 130
1. 90
2. 100
3. 110
4. 140
5. 130
5 * 124 = 620
Consider the arrangement
A B 140 D E
To maximize A , we need to minimize D & E
minimum value of D = min val of E = 140
140 * 3 = 420
620 - 420 = 200
Now we need to distribute 200 between A & B such that A <= B <= 140
therefore A = B = 200/2 = 100
What is the OA ?
