Answer 2

Answer:

$33\frac{1}{3} %$%

Step-by-step explanation:

Let the percentage decreased be X%

FROM THE QUESTION ,

150 lakhs  DECREASED to 100 lakhs

⇒ 1,50,00,000 - X% OF 1,50,00,000  = 1,00,00,000

⇒ 1,50,00,000 - $\frac{X}{100}$×1,50,00,000  = 1,00,00,000

⇒ 1,50,00,000 - 1,50,000X = 1,00,00,000

⇒ 1,50,00,000 -1,00,00,000=  1,50,000X

⇒50,00,000 = 1,50,000X

⇒X = $\frac{50,00,000}{1,50,000}$ = $\frac{500}{15}$ = $33\frac{1}{3} %$%
