Two successive increases of 15% each,
Two successive increases of 15% each, is by what percentage more then the two successive decreases of 12% each?(Rounded off to 2 decimal places)
प्रत्येक 15% की दो क्रमिक वृद्धि, प्रत्येक 12% की दो क्रमिक कमी से कितने प्रतिशत अधिक है? (दो दशमलव स्थान तक पूर्णांकित )
Detailed Solution & Logic
Correct Answer:
42.95%
दो क्रमिक 15% की वृद्धि
कुल वृद्धि =$ x + y + \frac{xy}{100} $
= 15 + 15 + $\frac{15 \times 15}{100}$ = 30 + 2.25 = 32.25%
दो क्रमिक 12% की कमी
कुल कमी $ = -12 - 12 + \frac{(-12)(-12)}{100} $ = -24 + 1.44 = -22.56%
कमी से वृद्धि कितने प्रतिशत अधिक है
सूत्र= $ \frac{32.25 - 22.56}{22.56} \times 100 $
$ = \frac{9.69}{22.56} \times 100 $
Answer = 42.95%
