Question

A factory produced 150 tons of steel in one year. The next year, the output increased to 180 tons. What is the percentage increase in the output? 17% 20% 30% 50% 75%

Answer 1

Answer:  Second option is correct.

Step-by-step explanation:

Since we have given that

Number of tons of steel in one year = 150 tons

Number of tons of steel next year = 180 tons

Increase in the number of tons is given by

$180-150\\\\=30\ tons$

We need to find the percentage increase in the output is given by

$\frac{Difference}{Original}\times 100\\\\=\frac{30}{150}\times 100\\\\=\frac{1}{5}\times 100\\\\=20\%$

Therefore, there is increase of 20% in the output.

Hence, Second option is correct.

Answer 2

180-150 = 30 ton increase

30/150 = 0.2 = 20 % increase
