Question

500
$500 \times \frac{80}{100} \times \frac{75}{100} \times \frac{90}{100}$
​

Answer 1

$\therefore 500 \times \frac{80}{100} \times \frac{75}{100} \times \frac{90}{100} = 270$

Step-by-step explanation:

$\therefore 500 \times \frac{80}{100} \times \frac{75}{100} \times \frac{90}{100} = 270$

$= 500 \times 0.8 \times 0.75 \times 0.9$

$= 500 \times 0.8 \times 0.675$

$= 500 \times 0.54$

$= 270$

$\therefore 500 \times \frac{80}{100} \times \frac{75}{100} \times \frac{90}{100} = 270$

By other method

$500 \times \frac{80}{100} \times \frac{75}{100} \times \frac{90}{100}$

$= 500 \times \frac{540000}{1000000}$

$= 500 \times 0.54$

$= 270$

$\therefore 500 \times \frac{80}{100} \times \frac{75}{100} \times \frac{90}{100} = 270$

Answer 2

Answer:

27000000/1000000 = 27/10=2.7

Step-by-step explanation:

• 500×80/100=40000/100
• 40000/100×75/100=300000/10000
• 300000/10000×90/100=27000000/1000000
• 27000000/1000000=27/10=2.7
