Question

Rahul was counting his colour pencils. Of his 50 pencils, a few are red, yellow, blue, and the rest are green. Find the percentage of each colour in his set.​

Answer 1

Answer:

If you give 4 pencils to each student, 20 pencils are left. If you give 5 pencils to each student 10 pencils are left. How many students are there?

If you look deep about the question, you get simple mathematic or use of simple imagination skill.

Suppose in your class,

you have N student

Now, If you give 5 pencils to each student

which comes out to be total pencil given to all student 5N

While 10 pencils are left,

So total pencil (5N+10)

the total pencil was given to students = (5N+10)

Now again, 4 pencils given to each student,

which comes out to be total pencil given to all student 4N, While 20 pencils are left,

So total pencil (4N+20).

So, total pencils,

(4N+20) = (5N+10)

on using simple mathematics, you get

(5N-4N) = (20-10)

N=10.

for checking your answer correct or not

put N=10 in (4N+20)

& (5N+10)

You get both come out to be equal, which is 60.

so there are 60 pencils given to all 10 students.
