I drew it for easy illustration.<br /><br />Important thing is to know that at 11am 2/3 of Tank A has been drained and 5/8 of Tank B has been drained. This means that 1/3 of the remaining level in Tank A is the same as 3/8 of the level in Tank B.<br /><br />Therefore, 1/3 of Tank A is equal to 3/8 of Tank B. We also know that Tank B is shorter than Tank A by 5 cm. <br /><br />From here, we can carry on the same calculation as illustrated in the main post. Which is,<br /><br /><br />(3/8) of B ----- (2/6) or (1/3) of A<br /><br />(1/8) of B ----- (1/3) of A divided 3 = (1/9) of A<br /><br />(8/8) of B (B's height) ----- 8 x (1/9) = (8/9) of A<br /><br />* Remaining (1/9) of A ----- 5 cm<br />(This is the difference in height between Tank A and B)<br /><br /><br />(9/9) of A (A's height) ----- 9 x 5cm = 45 cm<br /><br />Answer: 45 cmExcelEduservicehttps://www.blogger.com/profile/17134552650896445122noreply@blogger.comtag:blogger.com,1999:blog-6746419206932469118.post-85466609038158317602012-06-09T20:02:01.298+08:002012-06-09T20:02:01.298+08:00How are you able to draw such a diagram with accur...How are you able to draw such a diagram with accuracy.What clue is given in the question for you to draw the diagram.Please help.thanksMadhunoreply@blogger.com
