Question

find the original value of each of the following (i) a 90% increase gives 190 (ii) a 50%decrease gives 800 (iii) a 63%decrease gives 185​

Answer 1

$\boxed{\bf{\blue{\implies Answer:}}}$

• (1)Suppose original price is x
• $x + \frac{90x}{100} = 190$
• $190x = 19000$
• $x = 100$
• (2)Suppose original price is x
• $x + \frac{50x}{100} = 800$
• $150x = 80000$
• $x = 533.34$
• Similarly solve for (3)
