CBSE Questions for Class 6 Maths Algebra Quiz 4 - MCQExams.com

$$\dfrac{9}{4}$$ is a solution of the equation $$5x - 1= 8$$.
  • True
  • False
Let Arjun bought $$2$$ apple on $$Day \ 1$$.
Then he bought $$4$$ apple on $$Day \ 2$$.
He bought $$6$$ apple on $$Day \ 3$$. And so on.

So we can say, Arjun bought $$2\times N$$ apple on $$Day \ N$$.
Here $$"N"$$ in $$2\times N$$ represents
  • The number of apples
  • The number of days
  • $$N$$ is a constant
  • Can't say.
A non-variable/constant has a fixed value.
  • True
  • False
Select the equations where $$x = 1$$ is solution.
  • $$x+3 = 4$$
  • $$x-3 = 4$$
  • $$3x+3 = 6$$
  • $$3x-3 = 6$$
In a playground, kids are playing in the groups of $$5$$.

If there is one group of kids, then, total number of kids = $$5$$
If there is two group of kids, then, total number of kids = $$5+5 = 5\times 2$$
and so on.

So the total number of kids playing in the playground are
$$5 + 5+5+....= 5\times n$$
Here, the variable $$n$$ is
  • The number of groups
  • The number of kids
  • The number of toys
  • The number of games

  • $$x = 23$$
The non variable part in the expression $$2n$$ is
  • $$2$$
  • $$n$$
  • $$2n$$
  • None of the above.
What is the method of finding a solution by trying out various values for the variable called?
  • Trial method
  • Trial and error method
  • Substitution method
  • Testing method
Solve the equation $$x-10 = 5 $$ using trial and error method.

  • $$-x$$
  • $$y$$
  • $$36$$
  • $$-36$$
Evaluate using trial and error method:
$$2(x+5) = 10 $$
  • $$x = 0$$
  • $$x = 1$$

  • $$x= 15$$
  • $$x= 14$$
Choose the value of $$x$$ that satisfies the equation $$ 6x = 12$$.
  • $$x = 2$$
  • $$x = 3$$
  • $$x = 4$$
  • None of these
Use trial amd error method, find the value of $$t$$ if $$\dfrac{t}{4} = 4$$.
