Answer:
Number = 110 .
Step-by-step explanation:
Given : when 30% of a number is added to the number, the result is 143.
To find : Find the number described.
Solution : We have given 30% of a number is added to the number,
Let the number = x
According to question :
30% of a number x = \(\frac{30*x}{100}\) = \(\frac{3*x}{10}\).
Added to the number
x + \(\frac{3*x}{10}\) =143 .
On taking common denominator
\(\frac{10x+ 3*x}{10}\) = 143 .
\(\frac{13*x}{10}\) = 143 .
On multiplying both sides by 10 .
13 x = 143 *10.
13 x = 1430.
On dividing both sides by 13 .
x= 110.
Therefore, Number = 110 .
