Answer:
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 .
