Read the given statements carefully and select the correct option.
Statement I : The length of one parallel side of a
trapezium is 18 cm more than the other parallel side
and distance between them is 28 cm. If the area of
the trapezium is 1344 cm2, then the shortest parallel
side is 39 cm long.
Statement II : If each block of ice measures 5 cm ×
6 cm × 5 cm, then 250 block of ice can be put in a
box of dimensions 0.5 m × 0.5 m × 1.5 m.
AStatement I is true but Statement II is false.
BStatement I is false but Statement II is true.
CBoth Statement I and Statement II are true.
DBoth Statement I and Statement II are false.
Statement 2 tells that the blocks CAN BE PUT in the box or not so answer should be true.According to the solution, it says that a box of the volume REQUIRED is more than actual requirement. But the requirement is not asked.For example:- a small ball can be put in a small box AS WELL AS a big box. It can NEVER happen that the ball can be put in a small box but not in a big box. Son either question is wrong or solution is wrong.
