Which of the objects has/have a volume less than 30 mL? |
A) X only
B) Y only
C) X and Y only
D) X, Y and Z
Correct Answer: C
Solution :
When only X is added, volume of water increases 20 mL (from 30 mL to 50 mL) only. When Y is added, water level rises another 25 mL (from 50 mL to 75 mL). Hence, X and Y have a volume less than 30 mL. On the other hand addition of Z increases volume from 75 mL to 125 mL i.e., an increase of 50 mL.You need to login to perform this action.
