Answer:2

Explanation:

Given

Physics problem requires 20 min

Math problem require 10 min

suppose x question of Physics and y questions of Math are done

so according to the question

$x+y\geq 10\ldots 1$

Time require for x Physics problem
=20 x

Time require for y Math problem
=10 y

so,

$20 x+10 y\leq 120\ldots 2$

On solving (1) and (2)

we get
x=2 and
y=8

Maximum no of Physics question which can be solved is 2
