(i) Pollution done by cars = \(\frac { 600 }{ { 360 }^{ \circ } } \) × \({ 105 }^o\) = 175 unit

(ii) Difference in pollution done by school vehicles and trucks

\({ 90 }^o\) = \(\frac { 600 }{ { 360 }^{ \circ } } \) × \({ 90 }^o\) unit = 150 unit

(iii) Difference in poihition done by cars and bikes

\({ 60 }^o\) = \(\frac { 600 }{ { 360 }^{ \circ } } \) × \({ 90 }^o\) unit = 100 unit
