Ayaan has 20 stamps more than 3 times the number of stamps Affan has. If both of them together have 140 stamps. How many stamps does Affan have?

Let affan have x no. of stamps Then,

According to the question Ayaan has 20 stamps more than 3 times the number of stamps Affan has. Then,

x = 3x + 20

Now they both have 140 stamps all together. so,

x + 3x + 20 = 140

or, 4x = 140 - 20

or x = 120/4

or, x = 30

Therefore, Affan has 30 stamps .
