To make a cup of tea, the ratio of water to milk is

$3: 1$ . To make

$4$ cups of tea the ratio of water to milk is :

0%
$4 : 3$
0%
$12 : 1$
0%
$12 :4$
0%
$4 : 12$

Explanation

$cup$ of tea has Water to Milk Ratio

$W:M= 3:1$

where

$W$ and

$M$ are

$Water$ and

$Milk$

Now,

$4$ cups will have

$4$ times the

$Water$ and

$milk$ of a single

$cup$ .

So, the ratio will be

$=\dfrac{3\times 4}{1\times 4}$

$=\dfrac{12}{4}$ or

$12:4$ .

$=1 : 8$

In a school the total number of students are

$3200$ out of which

$1800$ are boys. Remaining are girls. Ratio of number of girls to boys is:

0%
$\dfrac{1400}{3200}$
0%
$\dfrac{9}{7}$
0%
$\dfrac{7}{9}$
0%
$\dfrac{1}{3}$

Explanation

The total number of boys in school

$=1800$
the total number of student

$=3200$
therefore the total number of girls

$=3200-1800=1400$

$\therefore$ , Ratio

$=\dfrac{\text{Girls}}{\text{Boys}}=\dfrac{1400}{1800}$

$\text{Ratio}=7:9$

I consume

$7$ chapatis at lunch and

$8$ chapatis at dinner. How many dozen chapatis do I consume in a leap year?

$\;450.5\:dozen$
0%
$\;460.5\:dozen$
0%
$\;457.5\:dozen$
0%
$\;467.5\:dozen$

Explanation

$1$ day I consume

$15$ chapatis

$=\displaystyle\frac{15}{12}dozen$ chapatis

$\;\;\;\;\;\therefore$ In

$\displaystyle\frac{15}{12}\times366\:dozen$ chapatis

$=457.5\:dozen$ chapatis.

Mala and Bala got

$75$ marks and

$25$ marks respectively in an examination. The ratio of the marks scored by Mala to the total marks obtained by both of them is

0%
$3 : 4$
0%
$3 : 1$
0%
$1 : 3$
0%
$4 : 3$

Explanation

Let

$x$ and

$y$ denote the marks obtained by Mala and Bala

$\therefore x=75$ and

$y=25$

Now, total marks

$=x+y= 75 + 25 = 100$

$\therefore$ Ratio of Mala's marks to that of total marks

$=x:\text{total marks} = 75 : 100 = 3 : 4$

Hence, option A is correct.

In an office, the working hours are

$10.30$ AM to

$5.30$ PM and in between

$\dfrac{7}{30}$
0%
$\dfrac{1}{14}$
0%
$\dfrac{14}{1}$
0%
$\dfrac{30}{7}$

Explanation

The offfice hours are from

$10.30 AM$ to

$5.30PM$ hence total office hours are

$7hours$ and lunch time hours is

$\dfrac{1}{2} hours$
ratio of office hrs to lunch time =

$\dfrac{7}{1/2}$
this gives ratio =

$14:1$

In a football match the ratio of total number of players of both the teams to the number of referees is:

0%
$\dfrac{10}{2}$
0%
$\dfrac{11}{2}$
0%
$\dfrac{22}{2}$
0%
$\dfrac{22}{1}$

Explanation

The total number of football player in

$1 team=11$
therefore in 2 teams the player must be

$2\times 11=22$
and

$refree =1$

$ratio=\dfrac{22}{1}$

If the cost of

$x$ metres of wire is

$d$ rupees, then what is the cost of

$y$ metres of wire at the same rate?

0%
Rs. $\displaystyle {\left (\frac{xy}{d} \right )}$
0%
Rs. $(xy)$
0%
Rs. $(yd)$
0%
Rs. $\displaystyle {\left (\frac{yd}{x} \right )}$

Explanation

Cost of

$x$ metres = Rs.

$d$
Cost of

$1$ metre = Rs.

$\left (\displaystyle \frac{d}{x} \right )$
Cost of

$y$ metres = Rs.

$\displaystyle {\left (\frac{d}{x}\, \times\, y \right )}$
= Rs.

$\displaystyle {\left (\frac{yd}{x} \right )}$

Rs. $5$
0%
none of these

Explanation

$\displaystyle 60\times \frac{2}{5}=Rs.24$

$\displaystyle 60\times \frac{3}{5}=Rs.36$

Difference = 36 - 24 = Rs.12

The ratio of

$Rs. 3$ and

$60$ paise is:

0%
$1 : 20$
0%
$5 : 1$
0%
$1:2$
0%
$20 : 1$

Explanation

$\textbf{Step1- Change Rs.3 into paise}$

$\text{Rs.3=3 $\times$ 100 }\text{paise}$

$\quad \quad \textbf{[Since 1 Ruppee = 100 paise]}$

$\Rightarrow Rs.3 = 300$

$\text{paise}$

$\quad \quad \text{.....eqn(i)}$

$\textbf{Step2- Find the required ratio}$

$\text{ Ratio of Rs.3 and 60 paise = } \cfrac{Rs.3}{\text{60 paise}}$

$\text{ Ratio of Rs.3 and 60 paise = } \cfrac{\text{300 paise}}{\text{60 paise}}$

$\quad \quad \textbf{[From eqn(i)]}$

$\text{ Ratio of Rs.3 and 60 paise = } \cfrac{300}{60}$

$\text{ Ratio of Rs.3 and 60 paise = }\cfrac{5}{1}$

$\text{ Ratio of Rs.3 and 60 paise = } 5:1$

$\textbf{Hence option B is correct}$
