A fruit sekker buts 50 boxes of mangoes each containing 100 m mangoes at the rate of ₹1200 per box he sells each mangoes for ₹20 find his total profit and profit %

Answers

Answer:

₹40000, 66.6%

Step-by-step explanation:

Given data

Number of boxes= 50

Cost per box= ₹1200

Total cost= 50*1200= ₹60000

Total number of mangoes in all 50 boxes= 50*100= 5000 mangoes

Cost price per mago= 60000/5000=  ₹12

Selling price per mango=  ₹20

profit = selling price- cost price

profit=  20-12

proft=  ₹8

Total profit = 8*5000

Total profit= ₹40000

%profit = 40000/60000*100

%profit= 0.666*100

%profit= 66.6%

Problem 2: Raylin wants to buy a new bike for $85. She already has $22 saved and her mom will
give her $2.50 for each chore she does. What is the least amount of chores Raylin must do in order
to save enough money to buy the bike?
Answer
22
23
24
25
26

Answers

○=> Correct option :[tex]\color{plum}\tt\bold{(d) \: 25}[/tex]○=> Steps to derive correct option :

Cost of a bike Raylin wants to buy = $85

Money Raylin already has = $22

Money she needs :

[tex] = \tt85 - 22[/tex]

[tex] = \tt\$63[/tex]

Thus, money Raylin still needs = $63

Money she gets from doing one chore = 2.50

Number of chores the needs to do :

[tex] = \tt \frac{63}{2.50} [/tex]

[tex]\color{plum} =\tt 25 \: chores[/tex]

Thus, Raylin needs to do 25 chores to be able to buy the bike.

Therefore, the correct option is (d) 25

Step-by-step explanation:

The computation of the probability that 2 people were excited without replacement is shown below:

There is a total of 20 people

out of which 16 are excited and the remaining 4 would be non-excited

in 10 years time a father Will be twice as old as his daughter.10 years ago he was six time as old as his daughter.How old is each now

Answers

Answer:

Step-by-step explanation:

let fathers age now be x

daughters age now be y

10 years hence

(x+10)= 2(y+10)

x+10 = 2y+20

x-2y=10

10 years ago

(x-10)= 6(y-10)

x-10 = 6y-60

x-6y=-50

x-2y=10

x-6y=-50

subtract the equations

4y=60

y=15 daughter's age now

substitute y in x-2y=10

so x=40 present father's age

pls mark brainliest

Answer:

Let the age 10 years ago of daughter be ( x years ) and age of father would be ( 6x years )

After 10 years, age of father = ( 6x + 10 + 10 )

= ( 6x + 20 ) years

And Age of daughter will be = ( x + 10 + 10 )

= ( x + 20 ) years

ATQ,

6x + 20 = 2( x + 20 )

=> 6x + 20 = 2x + 40

=> 6x - 2x = 40 - 20

=> 4x = 20

=> x = 5

Hence, Present age of daughter = ( x + 10 )

= ( 5 + 10 )

= 15 years

Present age of father = ( 6x + 10 )

= 6( 5 ) + 10

= 30 + 10

= 40 years
