Question

calculate the percentage increase or decrease if the mertro fare increase from rs 8 to rs 20​

Answer 1

Step-by-step explanation:

percentage increase=

$\frac{20 - 8}{8} \times 100$

$= \frac{12}{8} \times 100$

$= \frac{3}{2} \times 100$

$= 3 \times 50$

= 150

so there is 150% increase in the metro fare

Answer 2

Answer:

150℅

Step-by-step explanation:

Increase in price= 20-8=12

Let x be the percent increase

Therefore we can write

$x\% \: of \: 8 = 12$

$\frac{x}{100} \times 8 = 12$

$x = 150\%$
