Question

Sameer has stamp collection in which he has 142 less than 3 times the number of times Rohit has if both of them have same number of stamps how many stamps does Rohit have

Answer 1

Let the number of stamps rohit has be x
Then Sameer has (3x-143) stamps

As stated in the question, they have same number of stamps
So..
3x-142=x
3x-x=142
2x=142
x=71

So they both will have 71 stamps
