A7. Find the area of a trapezium whoseparallel sides are 12 cm and19cm and the distance betweenthem is 14cm.ince​

Answer»

{\large{\pmb{\sf{\underline{RequirEd \; Solution...}}}}}

{\pmb{\sf{\underline{Correct \: Question...}}}}

⋆ Find the area of a trapezium whose parallel sides are 12 cm and 19 cm and the distance between them is 14 cm.

⋆ This question says that there is a trapezium GIVEN whose parallel sides are given as 12 CENTIMETRES and 19 centimetres. And also provided that the distance between them(parallel sides) is 14 centimetres. Don't be confused that what is "distance between them" means here, distance between them means the attitude or height. And at last question asked that we have to find out the area of this trapezium. Let's solve this question!

{\pmb{\sf{\underline{Given \: that...}}}}

⋆ A trapezium is given.

⋆ Parallel sides = 12 cm and 19 cm

⋆ Distance between || sides = 14 cm

{\pmb{\sf{\underline{To \: find...}}}}

⋆ Area of trapezium

{\pmb{\sf{\underline{Solution...}}}}

⋆ Area of trapezium = 217 cm sq.

Point to be remember: Don't forget to add unit sq. whenever writing area of any shape, if you didn't write then marks would be deducted! (Here, unit means METRES, centimetres etc)

{\pmb{\sf{\underline{Using \: Concept...}}}}

⋆ Formula to find out the area of trapezium.

{\pmb{\sf{\underline{Using \: Formula...}}}}

{\small{\underline{\boxed{\sf{\star \: Area \: of \: trapezium \: = \dfrac{1}{2} \times h \times (a+b)}}}}}

{\pmb{\sf{\underline{Where...}}}}

⋆ h denotes height

⋆ a and b denotes parallel sides

{\pmb{\sf{\underline{Full \: Solution...}}}}

~ To solve this question we just have to imply the values according to the using formula that is of area of trapezium. Let us solve this question!

:\implies \sf Area \: of \: trapezium \: = \dfrac{1}{2} \times h \times (a+b) \\ \\ :\implies \sf Area \: of \: trapezium \: = \dfrac{1}{2} \times 14 \times (12+19) \\ \\ :\implies \sf Area \: of \: trapezium \: = \dfrac{1}{2} \times 14 \times 31 \\ \\ :\implies \sf Area \: of \: trapezium \: = \dfrac{1}{\cancel{{2}}} \times \cancel{14} \times 31 \\ \\ :\implies \sf Area \: of \: trapezium \: = 1 \times 7 \times 31 \\ \\ :\implies \sf Area \: of \: trapezium \: = 7 \times 31 \\ \\ :\implies \sf Area \: of \: trapezium \: = 217 \: cm^{2}

HENCEFORTH, 217 centimetres sq. is the area of trapezium whose height is 14 cm and parallel sides are 12 cm and 19 cm.

{\pmb{\sf{\underline{Figure...}}}}

⋆ Figure regards this question is given in attachment 1st. Kindly see from there.

Bhatya invested 800 on simple interest of rate 5%per annum . How many years will it take his money toreach * 1000 ?(A) 4 years (B) 5 years(C) 2 years(D) 20 years​

Answer»

➤ Given :-

Principle :- ₹800

Rate of interest :- 5%

Total Amount :- ₹1000

\:

➤ To Find :-

The time TAKEN to receive the MONEY back...

\:

★ How to do :-

Here, we are given with the principle amount, the rate of interest and the total amount received back at end of the time period. But, we are not given with the time taken to receive the money back from the BANK. We are asked to find the same. We have an appropriate formula to calculate the time period of this investment by which we can easily find the answer. But, we need the interest amount for finding that. So, first we should find the SIMPLE interest and then, we can solve for time. So, let's solve!!

\:

➤ Solution :-

Simple Interest :-

{\sf \leadsto \underline{\boxed{\sf Total \: Amount - Principle}}}

Substitute the given values.

{\tt \leadsto 1000 - 800}

Subtract the values to GET the interest amount.

{\tt \leadsto Rs \: \: 200}

\:

Now, let's find the time period of the investment.

Time :-

{\sf \leadsto \underline{\boxed{\sf \dfrac{SI \times 100}{P \times R}}}}

Substitute the given values.

{\tt \leadsto \dfrac{200 \times 100}{800 \times 5}}

Write the numerator and denominator in lowest form by cancellation method.

{\tt \leadsto \dfrac{\cancel{200} \times 100}{\cancel{800} \times 5} = \dfrac{1 \times 100}{4 \times 5}}

Multiply the remaining numbers on numerator and denominator.

{\tt \leadsto \cancel \dfrac{100}{20} = 5 \: years}

\:

{\red{\underline{\boxed{\bf So, \: option - (B) \: is \: the \: correct \: answer}}}}

━━━━━━━━━━━━━━━━━━━━━━━

\dashrightarrow Some related formulas :-

\begin{gathered} \small \boxed{\begin{array} {cc} \large \dag \: \sf More \: formulas \\ \\ \sf \bigstar \: Simple \: interest = \dfrac{P \times R \times T}{100} \\ \\ \sf \bigstar \: Principle = \dfrac{SI \times 100}{R \times T} \\ \\ \sf \bigstar \: Rate \: of \: interest = \dfrac{SI \times 100}{P \times T} \\ \\ \sf \bigstar \: Time = \dfrac{SI \times 100}{P \times R} \end{array}} \end{gathered}

The ratio of milk and water in a 60 litre mixture is 7: 3. Find the quantity of milk to beadded to the mixture to make the ratio 5 : 1.​

Answer»

Answer:

  • 48 litres of milk should be added to the mixture to make the ratio 5 : 1.

Step-by-step explanation:

Given that:

  • The ratio of milk and water in a 60 litre mixture is 7 : 3.

To Find:

  • Quantity of milk to be added to the mixture to make the ratio 5 : 1.

Let us assume:

  • Quantity of the milk be 7x.
  • Quantity of water be 3x.

According to the question:

\sf{\implies 7x+3x=60}

Adding,

\sf{\implies 10x=60}

Transposing 10 from LHS to RHS and changing its sign,

\sf{\implies x=\dfrac{60}{10}}

DIVIDING,

\sf{\implies x=<klux>6</klux>}

Hence,

  • x = 6

Therefore,

  • Quantity of milk = 7x = 7 × 6 = 42 litres
  • Quantity of water = 3x = 3 × 6 = 18 litres

Now, let us assume:

  • Quantity of milk to be added be n.

Then, according to the question:

\sf{\implies\dfrac{42+n}{18}=\dfrac{5}{1}}

\sf{\implies\dfrac{42+n}{18}=5}

Transposing 8 from LHS to RHS and changing its sign,

\sf{\implies42+n=5\times18}

Multiplying,

\sf{\implies42+n=90}

Transposing 42 from LHS to RHS and changing its sign,

\sf{\implies n=90-42}

Subtracting,

\sf{\implies n=48}

Hence,

  • n = 48

Therefore,

  • Quantity of milk to be added = n = 48 litres
