# 13.A student was asked to calculate the surface area of a cube. He calculated the volume.The reason (s) of error in calculation is/areA. the student finds the class boring as he does not like Mathematics classB. the student is not fit to study in that classC. the student is not able to understand the concept of surface area and volumeD. The student has understood the concept of surface area and volumeSelect the correct answer using the codes given below.B and C D A and B C

D.

C

The student is not able to understand the concept of surface area and volume. So, the student finds volume besides of area.

14.

In a meeting,"$\frac{4}{25}$ of the members were female. What percent of the members was this?

• 24%

• 4%

• 16%

• 40%

C.

16%

Let the total number of members in meeting =$x$
Then, the total number of females in meeting=$\frac{4x}{25}$

Required percentage =$\frac{Numberoffemales}{Totalnumberofmembers}×100$

$⇒\frac{\frac{4x}{25}}{x}×100%=16$

15.

Which one of the following is not a mathematical process?

• Memorisation

• Estimation

• Measurement

• Visualisation

A.

Memorisation

16.

A shop reduced its prices by 10%. What is the new price of an item which was previously sold for $₹$500?

• $₹$550

• $₹$450

• $₹$400

• $₹$510

B.

$₹$450

Given, the original price of an item=$₹500$

and reduced percentage =$10%$

$\therefore$New price item=$originalprice×\frac{\left(100-reducedpercentage\right)}{100}$

=$500×\frac{\left(100-10}{100}$

=$500×\frac{90}{100}$=$₹450$

17.

The purpose of a diagnostic test in Mathematics is

• to give feedback to the parents

• to fill the progress report

• to plant the question paper for the end term examination

• to know the gaps in children's understanding

D.

to know the gaps in children's understanding

The assessment is done in order to know about the gaps the learners have in their knowledge structure. Based on that assessment tests the teacher gets an understanding that how much further help the learners require.

18.

A teacher has taught measurement of area to class VIII children, but many of her students are confused between the usage of different units of area and volume. What could be the reason for such a confusion in children?

• The children have not memorised different units

• Different units have been introduced all together without relating them with daily life

• The concept of measurement of area is a difficult topic for a class VIII learner

• The children did not know the use of units for area

B.

Different units have been introduced all together without relating them with daily life

19.

"Errors play a crucial role in learning of Mathematics." This statement is

• True, because errors reflect the thinking of child

• false, because mathematics is exact

• true, because errors provide feedback about the marks they obtained

• false, because errors occur due to carelessness

A.

True, because errors reflect the thinking of child

The errors are the windows of a child's thinking, the error they make represent the way they are thinking with respect to an idea.
