State true or false:

Sum of

$2$ and

$p$ is

$2p$

0%

0%
False

Explanation

Sum of

$2$ and

$p$ will be

$2+p$ .

$2p$ is the product of

$2$ and

$p$

Hence, the given statement is false.

Arpita's present age is thrice of Shilpa. If Shilpa's age three years ago was

$x$ . Then Arpita's present age is

0%
$3(x-3)$
0%
$3x+3$

$\dfrac{9}{5}$ is the solution of the equation

$4X-1=8$

0%
True
0%
False

Explanation

$4 \times \dfrac{9}{5}=8$

$\dfrac{36}{5}=8$
But,

$\dfrac{36}{5}\neq8$

Hence,

$\dfrac{9}{4}$ is the solution of the given equation, not the

$\dfrac{9}{5}$

Which of the sign should always be there in an equation?

0%
$=$
0%
$\displaystyle \neq$
0%
$\displaystyle >$
0%
$\displaystyle <$

Explanation

An equation is a mathematical statement that two things are equal. It consists of two expressions, one on each side of an 'equals' sign. For example

$x=y$ is an equation where two expressions

$x$ and

$y$ are equal.

Hence,

$=$ sign should always be there in an equation.

Frame the statement "Twice a number decreased by

$119$ equals

$373$ " into an equation.

0%
$2y + 119 =373$
0%
$3y - 119=373$
0%
$2y - 119=373$
0%
None of the above.

Explanation

Let

$y$ be the number.

According to the question,
Twice a number

$y$ , decreased by

$119$ means

$2y-119=373$ .

So, option

$C$ is correct.

Sumeet guessed a number

$x$ and then he added

$30$ to it. Give the expression for double of it.

0%
$2(x+30)$
0%
$\dfrac{1}{2(x+30)}$
0%
$2x+30$
0%
$x+60$

Explanation

According to the question,
The expression is

$x+30$ .

$\therefore$ double of it will be

$2(x+30$ ).

So. option

$A$ is correct.

Frame the given statement into a mathematical expression: "Thrice of a number increased by

$150$ ."

0%
$150-x$
0%
$3x-150$
0%
$3x+150$
0%
None of these

Explanation

Let

$x$ be the required number.

$\therefore$ thrice of a number shall be

$\displaystyle 3\times x=3x$ .

According to the question, if it is increased by

$150$ ,

the number would be

$\displaystyle (3x+150)$ .

Frame the statement into an equation:

Adding

$16$ to

$3$ times

$x$ is

$39$ .

0%
$\displaystyle 3x-16=39$
0%
$\displaystyle 3x+16=-39$
0%
$\displaystyle -3x+16=39$
0%
$\displaystyle 3x+16=39$

Explanation

$3 \times x=3x$

As per the given condition,

Adding

$16$ to

$3x$ results in

$16+3x=39$

So, option

$D$ is correct.

Convert the statement into an equation : Adding

$14$ to

$9$ times

$y$ is

$89$ .

0%
$14y+9=89$
0%
$14+9y=89$
0%
$14-9y=-89$
0%
$14+y=89$

Explanation

According to the question,

$9$ times

$y$ means

$9 \times y = 9y$ .

Adding

$14$ to it means

$9y+14$ .

$\therefore$ the equation is

$9y+14=89$ .

Convert this statement in mathematical form.
Twice of remainder when 8 is subtracted from a number is 10.

0%
$2x-8=10$
0%
$2(x-8)=10$
0%
$\dfrac{2x}{8}=10$

let number be

$x$ ,then remainder

$=x-8$

$2(x-8)=10$

$12$ times a number is

$4$ less than the

$5$ times the number. Write an equation representing the statement given.

0%
$12x -4 = 5x$
0%
$12x+4 = 5x$
0%
$12+ 4x= 5$
