Question

A plastic bin contains red yellow and green keychains out of 350 keychains 10% or yellow off the remaining keychains three sets are green how many red keychains or inside the bin

Answer 1

Answer:

The question is not comprehensive, the comprehensive question is:

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key chains, 3/5 are green. How many red key chains are inside the bin?

There are 126 red key chains in the plastic bin

Step-by-step explanation:

The plastic bin contains keychains of red, yellow and green colours.

According to the question, the total keychains in the bin are 350.

10% of this keychains are yellow i.e. 10/100 × 350 = 35

Thus, 35 keychains are yellow in colour.

This means, we have 350 - 35 = 315 keychains consisting of red and green colours left.

The question further says that 3/5 of the remaining keychains (315) are green i.e. 3/5 × 315 = 945/5 = 189

Thus, there are 189 green keychains in the bin.

To get the number of red keychains in the plastic bin, we add the number of yellow and green keychains, and subtract the sum from the total keychains (350).

We have 35 (yellow) + 189 (green) = 224 yellow and green keychains.

Hence, red keychains = 350 (total keychains) - 224 (yellow and green)

= 126 red keychains

There are 126 keychains in the plastic bin.

Answer 2

Your question was not properly constructed. Below is what you probably intended:

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key chains, 3/5 are green. How many red key chains are inside the bin?

Answer: The quantity of red keychains in the bin is = 126

Step-by-step explanation:

First of all, we must note that that the total keychains of different colours in the plastic bin is 350.

Now we were informed that 10% of the total of 350 coloured keychains are yellow keychains. We will calculate to find out the actual quantity of yellow keychains that made up the 350 keychains in the plastic bin. Since the percentage of the yellow keys is = 10%, the actual quantity of yellow keys=

10/100 × 350 = 35 yellow keychains.

Therefore, there are 35 yellow keychains in the bin.

Again, we learnt that 3/5 of the remaining keychains are green. If this is so, then we will simply subtract the number of yellow keys in the bin from the total number of keys therein and multiply the result by 3/5 to find the actual quantity of green keys in the bin. That is:

350 total - 35yellow

= 315 keychains (green+red)

Then, 3/5 of 315

= 3/5 × 315 = 189 green keychains.

Now, to find the quantity of red keychains that are in the bin, we will simply subtract the quantity of green keychains from the total sum of red and green keychains excluding yellow keychains.

That is:

315(green+red) - 189(green)

= 126 red keychains.

Therefore, the quantity of red keychains in the bin is 126
