Question

If there are 200 balls in a bag out of which 99% are res balls , how many red balls will ytou remove so that out of the remaining balls in teh bag , only 98% are red balls

Answer 1

Only two balls have to remove

Answer 2

Answer:

Number of red balls needed to be removed from the bag = 2

Step-by-step explanation:

Total number of balls in the bag are given to be 200

Now, it is said that 99% of the total balls are of red color

⇒ Number of red balls in the bag = 99% of 200

                                                        = 0.99 × 200 = 198

Now, percentage of red balls required in the bag = 98%

Number of 98% red balls in the bag = 98% of 200 = 196

Now, Number of red balls in the bag = 198 and number of red balls needed in the bag = 196

So, number of red balls needed to be removed from the bag = 198 - 196 = 2
