Answer:

Option (A) 160

The Number is 160.

Step-by-step explanation:

Given :

65% of a number reduced by 65 is 39

To find :

The number

Solution :

Consider the number as y

\bigstar \: \boxed{\tt{(65\% \: of \:y) - 65 = 39 }}

\tt{\implies} \:  \left(\dfrac{65}{100} \times y\right) - 65 = 39 \\  \\ \tt{\implies} \: \dfrac{65y}{100} - 65 = 39 \\  \\ \tt{\implies} \: \dfrac{65y}{100}  = 39 + 65 \\  \\ \tt{\implies} \: \dfrac{65y}{100}  = 104 \\  \\ \tt{\implies} \:65y = 104 \times 100 \\  \\ \tt{\implies} \:65y = 10400 \\  \\ \tt{\implies} \:y =  \dfrac{10400}{65} \\  \\ \tt{\implies} \:y = 160

The Number = 160

\therefore The Number is 160.

  • किसी संख्या के 65% में से 65 घटाने से 39 प्राप्त होता है .

\LARGE\underline{\underline{\sf To\:Find:}}

  • संख्या का भाग कितना है = ?

\LARGE\underline{\underline{\sf Solution:}}

\large\underline{\underline{\sf According\:to\: Question:}}

मानले ,

संख्या का भाग x है

\large\implies{\sf (65\%\:of\:x)-65=39}

\large\implies{\sf \left(\dfrac{65}{100}×x\right)-65=39}

\large\implies{\sf \dfrac{65x}{100}=39+65 }

\large\implies{\sf \dfrac{65x}{100}=104}

\large\implies{\sf 65x=104×100}

\large\implies{\sf 65x=10400 }

\large\implies{\sf x=\dfrac{10400}{65}}

\large\implies{\sf x=160}

\LARGE\underline{\underline{\sf Answer:}}

•°• उस संख्या का भाग 160 है |
