A purchased 3 dozen apples at Rs. 240 per dozen, Two dozen apples at Rs, 360 per dozen and 5 dozen apples at Rs. 180 per dozen. Find the average cost of the apple.

Answer»

Given;

purchased,

  • 3 DOZEN apples at Rs 240/dozen
  • 2 dozen apples at Rs 360/dozen
  • 5 dozen apples at Rs 180/dozen

To Find;

  • Average cost of the Apple

Solution;

  • Total cost of 3 dozen apples = 3 × 240

= Rs 720

  • Total cost of 2 dozen apples = 2 × 360

= Rs 720

  • Total cost of 5 dozen apples = 5 × 180

= Rs 900

  • total NUMBER of apples purchased

= (3 × 12)+(2 × 12)+(5 × 12)

= 36 + 24 + 60

= 120

Therefore;

Total cost of all the apples = 720 + 720 + 900

= Rs 2340

Formula Used;

  • Average cost of apples

= total cost / total number of apples

Substituting the VALUES;

Average cost = 2340/120

= Rs 19.5

Conclusion;

  • The average cost of the Apple is Rs 19.5

Q.3 A well is dug out whose radius is 4.2m and depth is 38m. The earth taken out from well is spread all over a rectangular field whose dimensions are 130m * 115m . Find the rise in the level of field.​

Answer»

ong>GIVEN :-

  • A well is dug out WHOSE radius is 4.2m and depth is 38m.
  • It is then spread all over the rectangular field whose DIMENSIONS are 130m×115m.

TO FIND :-

  • Rise (height) in the level of field .

TO KNOW :-

★ Volume of Cuboid = πr²h

★ Volume of Cuboid = L × b × h

SOLUTION :-

For well ,

  • Radius(r) = 4.2m
  • Height(H) = 38m

Well is in the form of Cylinder.

Volume of well dugged out = πr²H

ㅤㅤㅤㅤㅤㅤㅤㅤ= (22/7) × (4.2)² × 38

ㅤㅤㅤㅤㅤㅤㅤㅤ= (22/7) × 17.64 × 38

ㅤㅤㅤㅤㅤㅤㅤㅤ= 14747/7

ㅤㅤㅤㅤㅤㅤㅤㅤ= 2106.7 m³ -----(1)

__________________________

For field ,

  • Length (l) = 130m
  • Bredth (b) = 115m

Field is in the form of Cuboid.

Volume of field = l × b × h

ㅤㅤㅤㅤㅤ ㅤㅤ= 130 × 115 × h

ㅤㅤㅤㅤㅤㅤ ㅤ= 14950h m³ -------(2)

♦ When same amount of earth is digged out and spread all over the field , total volume in both the cases will be same.

So, equating (1) and (2) ,

→ 2106.7 = 14950h

→ h = 2106.7/14950

→ h = 0.14m = 14cm

Hence , there is a rise of 14cm or 0.14m in the field.

MORE TO KNOW :-

★ Volume of Cone = (1/3)πr²h

★ Volume of CUBE = edge³

★ Volume of Sphere = (4/3)πr³

★ Volume of Hemisphere = (2/3)πr³

prove that if x and y are both odd positive integers then x square + y square is even but not divisible by 4​

Answer»

Given:-

  • x and y are ODD positive integers.

To Prove:-

  • x² + y² is even but not divisible by 4.

step-by-step SOLUTION:-

Let the two odd NUMBERS be (2a+1) & (2b+1) because if we add 1 to any even no. it will be odd.

x²+y²

  • → (2a + 1)² + (2b + 1)²
  • → (4a² + 4a + 1) + (4b²+ 4b + 1)
  • → 4(a² + b² + a + b)+2

4 Is not a multiple of 2 it means CLEARLY that 4 is not multiple of x²+y² , so x²+y² is even but not divisible by 4.

Hence proved.!!
