Answer 1

sorry i am some weak in math

Answer 2

Answer:

Step-by-step explanation:

Let x is the amount of money i have with myself and y is the number of students in class.

Rs. 3 were given to all the students. Therefore, amount distributed

= Rs. 3y

According to first condition,

x - 3y = 30

Now, Rs. 4 are distributed.

Therefore, total amount distributed

= Rs. 4y

According to second condition,

4y - x = 10

Adding both equations we get

y = 40.

Substituting y= 40 in equation first

We get

x-3(40)=30

x-120=30

x=150

Therefore, the amount I had with myself is Rs. 150 and the number of students in the class is 40.
