Explanation

We know that:

$1\ hour=60\ mins$

$\therefore 3\ hours=60\times3=180\ mins$ (By unitary method)

$In\ 1\ min\ amount\ of snow\ that\ falls=2\ tons$

$In\ 180\ minutes\ amount\ of\ snow\ that\ falls=180 \times 2=360\ tons$ (By Unitary method)

Two equivalent ratios of

$\dfrac{14}{3}$ are

0%
$\dfrac{64}{12}$ , $\dfrac{126}{24}$
0%
$\dfrac{28}{6}$ , $\dfrac{42}{9}$
0%
$\dfrac{42}{9}$ , $\dfrac{64}{6}$
0%
$\dfrac{98}{21}$ , $\dfrac{126}{24}$

Explanation

$\displaystyle \frac{14}{3}=\frac{14\times 2}{3\times 2}$

$\displaystyle =\frac{28}{6}$ and

$\displaystyle \frac{14}{3}=\frac{14\times 3}{3\times 3}$

$\displaystyle =\frac{42}{9}$

$\Rightarrow \dfrac{28}{6}, \dfrac{42}{9}$ are Equivalent ratios of

$\displaystyle \frac{14}{3}$

$1400$

Explanation

Number of cookies baked

$=2000$
Number of cookies sold

$=600$

Explanation

Weight of

$4$ cups of sugar

$= 920\ g$

$\therefore$ Weight of

$1$ cup of sugar

$= (920 \div 4)g = 230\ g$
Weight of

$1$ glass of sugar

$= 300\ g$
Required difference

$= (300 - 230)g = 70\ g$ .

A pole is painted red and white. The red portion is

$= 5.4\ m$
So, total length of pole

$= (1.8 + 5.4)m$

$= 7.2\ m$ .

Hence,

$Op-B$ is correct.

0%
None of these

Explanation

${\textbf{Step -1: Converting rupees to paise}.}$

${\text{We know that, 1 Rupee = 100 paise}}$

$\therefore {\text{ 5 Rupees = }}\dfrac{{{\text{5 }} \times {\text{ 100}}}}{{\text{1}}}{\text{ paise}}$

$\Rightarrow {\text{ 5 Rupees = 500 paise}}$ $\quad \quad \text{......eqn (i)}$

${\textbf{Step -2: Substitute the above result and find the required ratio}.}$

${\text{Ratio of 5 Rupees}}{\text{ to 50 paise }}$ $= {\text{ }}\dfrac{{{\text{5 Rupees}}}}{{{\text{50 paise}}}}$

$= {\text{ }}\dfrac{{{\text{500 paise}}}}{{{\text{50 paise}}}}$ $\quad \quad \textbf{[From eqn (i)]}$

$= {\text{ 10:1}}$

${\textbf{Thus, the ratio of 5 Rupees to 50 paise is 10:1}.}$
