Sachin is being tested for his eyesight by an optician.Now, letâs read the given information carefully, and find out the position of Sachin.Sachin sits 3 m in front of a plane mirror, and looks at the image of the chart of letters, which seems to be 7 m in front of him.This means the distance between the mirror and the image of the chart is (7 m â 3 m = 4 m). If the image of the chart is 4 m behind the mirror, then the actual chart is placed 4 m in front of mirror.Now the chart is placed 4 m in front of the mirror, and Sachin is sitting 3 m in front of the mirror. That means the chart is placed (4 m â 3 m = 1 m) behind Sachin. Hence, the right answer is Option A.

A as image is as far behind the mirror as Object is in front of it.
In this case Sachin is 3 m in front of the mirror and the object seems to be seven meters ahead.
As Sachin is 3 m in front of the mirror that means object is (7-3) = 4 m behind the mirror.
As image is as far behind the mirror as Object is in front of it, It means chart is 4 meters in front of the mirror.
( 4 - 3 ) = 1 m behind Sachin as Sachin is also in front of the mirror.
Hope that answers your question !

Why will it be D? It should be C, because the Vaseline blocks the stomata of the leaves, and thus blocks the surface for transpiration, so water droplets will not appear on those leaves, but the uncovered leaves were not stained or covered with anything, so the transpiration process in those leaves should stay normal.
