Question

total enrolement of a school is 840. of these 2/7 are girls and the rest are boys. find the fraction of boys in the school. also, find the number of girls and number of boys in the school​

Answer 1

Answer:

Although there are several ways to solve this ,

I will not get into those 'x' business.

We know 4/5 of the children are boys therefore the remaining 1/5th must be girls.

Now it is being said the no. Of girls is 200.

Hence , if 1/5th corresponds to 200.

Then the whole part or the total number of students will be equal to 200*5=1000.

And the number of boys would be 1000–200= 800.

*This numerical problem resembles the current situation of engineering colleges in India* XD

hence, ' beti bachao beti padhao.'
