Cards are natural numbers from 4 to 56. A card is drawn randomly find the prob-ability of getting i) Factors of 60 ii) Multiple of 12 iii)Two digit numberwhose sum is 7 iv) perfect square.​

Answer»

Solution!!

The concept of probability has to be used here. Given that the cards are natural numbers from 4 to 56.

So, the cards are 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55 and 56.

Hence, TOTAL number of cards = 53

A card is drawn randomly. The probability that the card is :-

(i) factor of 60 is 9/53

Explanation:

Factors of 60 from 4 to 56 are 4, 5, 6, 10, 12, 15, 20, 30 and 60.

There are total 9 factors.

Number of favourable outcomes = 9

Probability = Number of favourable outcomes ÷ Total number of outcomes

Probability = 9/53

(ii) multiple of 12 is 4/53

Explanation:

Multiples of 12 from 4 to 56 are 12, 24, 36 and 48.

There are total 4 multiples.

Number of favourable outcomes = 4

Probability = Number of favourable outcomes ÷ Total number of outcomes

Probability = 4/53

(iii) two digit number whose sum is 7 is 5/53

Explanation:

Two digit numbers whose sum is 7 from 4 to 56 are 16, 25, 34, 43 and 52.

There are total 5 such numbers.

Number of favourable outcomes = 5

Probability = Number of favourable outcomes ÷ Total number of outcomes

Probability = 5/53

(iv) perfect square is 6/53

Explanation:

Perfect squares from 4 to 56 are 4, 9, 16, 25, 36 and 49.

There are total 6 perfect squares.

Number of favourable outcomes = 6

Probability = Number of favourable outcomes ÷ Total number of outcomes

Probability = 6/53

The product of two consecutive odd integers is 35.form the equation

Answer»

ANSWER:

−7and−5 or +5and+7

EXPLANATION:

LET the first number be 2n−1

the second number must be 2n+1

We are told that the product of the numbers is 35 ∴(2n−1)(2n+1)=35

4n2−1=35

4n2=36

N2= 9→n=±3

Then, EITHER, first number =(6−1)=+5

second number =5+2=+7

or

First number =(−6−1)=−7

second number = −7+2=−5

If 2 pumps working 7 hours a day can lift 2,800 gallons of wayer in 20days, in how many days can 20 pumps working 9 hours a day life 3,000gallons of water?​

Answer»

Given that

2 pumps working 7 HOURS a day can lift 2,800 gallons of water in 20 days

To Find :-

In how many days can 20 pumps working 9 hours a day life 3,000 gallons of water?

Solution :-

2 pumps working 7 hours a day = pumps WORK for 14 hours per day. ------(1)

Again,

2800 gallons of water lift in 20 days.

  • It means, 140 gallons of water lift in 1 day. ------(2)

From equation (1) and (2), we concluded,

  • 140 gallons of water is lifted in 14 hours.

So, In 1 hour, 140 ÷ 14 = 10 gallons of water is lifted.

According to STATEMENT,

20 pumps working 9 hours per day = pumps works for 180 hours per day.

Now,

  • In 1 hour, 10 gallons of water is lifted.

So,

In 180 hours,

  • 180 × 10 = 1800 gallons of water is lifted.

It implies,

  • 1800 gallons of water is lifted in 1 day.

So,

3000 gallons of water is lifted in

\:  \: \rm  =  \:  \: \dfrac{3000}{1800}

\:  \: \rm  =  \:  \: 1.666 \: days

1) A village population of 5000. It requires 120L of water per head perday It has a tank measuring 20m by 20m by 3 m. For how many daysthe water of this tank will last?​

Answer»

Answer: 2 days

Given that,

  • A village of population of 5000 PEOPLE and each people REQUIRES 120L of water per day.

Also,

  • The village has a tank which measures 20m by 20m by 3m. Looking at the dimension, It is CLEAR that the tank is in the shape of a cuboid.

Now, lets find the total amount of water REQUIRED by the village per day, which is given by:-

⇒ Water required by 1 person × Population

⇒ 120 × 5000

600,000 L

We know, the VOLUME of a cuboid is given by:-

⇒ Length × Breadth × Height

⇒ 20 × 20 × 3

⇒ 400 × 3

1200

But, we need the volume of the tank in litres in order to find the number of days it is gonna last for, so 1 = 1000 L , hence

Volume of Tank = 1,200,000 L

Now, the number of days the tank is gonna last for is given by:-

⇒ Volume of Tank ÷ Amount of water required per day

⇒ 1,200,000 / 600,000

2

Hence, the tank is gonna last for 2 days.

. There is 160 days ration for 540 persons in a fort. After 10 days, 60 more personsjoin them. For how many days will theration sufficient at the same rate?​

Answer»

Given :-

  • Number of days RATION can last = 160 days
  • Number of PERSONS = 540
  • After 10 days, 60 more persons jöin.

Aim :-

  • To find the number of days the food will last if 60 more persons are included.

Answer :-

Let us tabulate the given hints.

\begin{array}{|c|c|}\cline{1-2} \bf x & \bf y \\\cline{1-2}\bf Number\ of\ men & \bf Number\ of\ days \\\cline{1-2} \bf 540 & \bf 160 \\\cline{1-2}\bf 540+60 & \bf ?\\\cline{1-2}\end{array}

if x ↑ then y ↓ and vice versa.

⇒ If the Number of men increases, the Number of days the ration lasts decreases.

Hence, x and y are in inverse proportion.

Let us assume the number of days the food will last when 60 more persons JOIN as y₂

  • \sf x_{1} = 540\:men
  • \sf x_{2} = 540 + 60\:men
  • \sf y_{1} = 160\:days

\implies \sf y_{2} = \dfrac{x_{1} \times y_{1}}{x_{2}}

By substituting the values, we get :

\implies \sf y_{2} = \dfrac{540 \times 160}{540 + 60}

\implies \sf y_{2} = \dfrac{540 \times 160 }{600}

\implies \sf y_{2} =  \dfrac{54\not0 \times 16\not0}{6\not0\not0}

\implies \sf y_{2} = 9 \times 16

\implies \sf y_{2} = 144

Therefore, the food will last for 144 days, if 60 more people join the fort.

[x implies the number of men and y implies the number of days.].

  • \longrightarrow \sf \dfrac{x_{1}}{x_{2}} = \dfrac{y_{2}}{y_{1}}
