Question

What approximate value should come in the place of question mark (?) in the following question? 29.9% of 499.99 - 49.93% of 399.99 + 69.92% of 199.99 = ?​

Answer 1

Answer:

? = 90

Step-by-step explanation:

29.9% of 499.99 - 49.93% of 399.99 + 69.92% of 199.99 = ?

⇒ 30% of 500 - 50% of 400 + 70% of 200 = ?

⇒ (30/100) × 500 - (50/100) × 400 + (70/100) × 200 = ?

⇒ 150 - 200 + 140 = ?

⇒ 290 - 200 = ?

⇒ ? = 90
