Question:༶•┈┈⛧┈♛

If 75% of a number is added to 75, the result is the number again. Find the number

Solution:｡.｡:∞♡*♥

Let the no. be x.

Given:☆♬○♩●♪✧♩　　

• ☆ 75% of x + 75 = x

then, ▩▩

A/Q, ◒◒

75/100 × x + 75 = x

3x/4+ 75 = x

3x/4 - x = -75

3x-4x /4 = -75

-x/4 = -75

-x = -75×4

x = 300

so, -: ✧ :-゜・．

the required no. is 300.

To Verify:»»——⍟——««

75% of x + 75 = x

75/100 × 300 + 75 = 300

75 × 3 + 75 = 300

225 + 75 = 300

300 = 300

HENCE VERIFIED

Analysis:»»————>

we have to let the required number be x. then according to question 75% of the no. that we have let x. if we added the no. 75, then the result is that we have let x.

I hope it's helpful for you

Answer 2

//Assume :

Let's assume that number is p.

//Solution :

$\therefore \: by \: given \: conditions \\ (\frac{75}{100} \times p) + 75 = p \\ \implies \: 75( \frac{p}{100} + 1) = p \\ \implies \: 75( \frac{p + 100}{100} ) = p \\ \implies \: 75p + 7500 = 100p \\ \implies \: 25p = 7500 \\ \therefore \: p = 300$
