Question

Anandi things of a number and subtract 5 from it. She multiplies the result by 8 the result now obtained is 3 times the same number she thought of what is the number? ​

Answer 1

Answer:

Let us assume the number thought by Anandhi to be 'x'.

She subtracts 5 from it.

⇒ x - 5

Now she multiplies the result by 8.

⇒ ( x - 5 ) × 8 = 8x - 40

The result now obtained is 3 times the number she had thought of.

⇒ 3x = 8x - 40

⇒ 40 = 8x - 3x

⇒ 40 = 5x

⇒ 8 = x

Verification:

⇒ 8 - 5 = 3

⇒ 3 × 8 = 24

⇒ 24 = 3 × 8

Hence Verified !!

Hence Anandhi has thought of the number 8.

Answer 2

$\huge{\pink{\green {\sf\boxed{ANSWER = she \:thought\: 8 }}}}$

$\huge{\pink {\sf\underline{Step\: by\: step\: explanation-:}}}$

Let Anandi thinks number be ${x}$

Subtracted from = ${</strong><strong>x</strong><strong> </strong><strong>-</strong><strong> </strong><strong>5</strong><strong>}$

Multiply ${x - 5}$ by 8

= ${8x - 40}$

$\Large\boxed{According\: to\: question :-}$

=> ${8x - 40 = 3x}$

=>${8x - </strong><strong>3x</strong><strong> = </strong><strong>40</strong><strong>}$

=> ${</strong><strong>5x</strong><strong> </strong><strong>=</strong><strong> </strong><strong>40</strong><strong>}$

=> $</strong><strong>x</strong><strong>=\frac</strong><strong>{</strong><strong>40</strong><strong>}</strong><strong>{</strong><strong>5</strong><strong>}</strong><strong>$

=>$</strong><strong> </strong><strong>\</strong><strong>green</strong><strong> </strong><strong>{</strong><strong>x</strong><strong> </strong><strong>=</strong><strong> </strong><strong>8</strong><strong>} </strong><strong> </strong><strong>$

$\Large\boxed{</strong><strong>Hence</strong><strong>,</strong><strong>She</strong><strong>\</strong><strong>:</strong><strong> </strong><strong>thought</strong><strong> </strong><strong>=</strong><strong> </strong><strong>8</strong><strong>}$

$</strong><strong> </strong><strong>\Large\boxed{</strong><strong>SOLVED</strong><strong>}</strong><strong>$
