Answer:
7 pieces
Explanation:
let the initial number of papers be x
he got extra three more papers which makes the total number of papers near Daniel as x+3
now all these papers are cut into half which means 2(x+3) is the total number half piece papers Daniel got which was given as 20.
2(x+3)=20
x+3=10
x=7
There are 7 pieces of paper with him initially.
