Answer 2

Answer:

50

Step-by-step explanation:

Given : When 70 is added to 70% of a number, the result is 70% of 150

To Find : Number

Solution:

let the number be x

70 % of a number = $70 \% \times x$

We are given that When 70 is added to 70% of a number, the result is 70% of 150

So, $70+70 \% \times x=70\% \times 150$

$70+\frac{70}{100}x=\frac{70}{100} \times 150$

$70+\frac{70}{100}x=105$

$\frac{70}{100}x=105-70$

$\frac{70}{100}x=35$

$x=35 \times \frac{100}{70}$

$x=50$

Hence the number is 50
