Answer : A)7  □214→(2+1+4)=7   48→(4×8)=32  △27→(7−2)=5  ∴△ □6754239=△ (6+7+5+4+2+3+9)  =△ 36=△(3×6)  =△18=(8−1)=7✓

$$\left.{Answer}\::\:{A}\right)\mathrm{7} \\ $$$$\Box\mathrm{214}\rightarrow\left(\mathrm{2}+\mathrm{1}+\mathrm{4}\right)=\mathrm{7} \\ $$$$ \mathrm{48}\rightarrow\left(\mathrm{4}×\mathrm{8}\right)=\mathrm{32} \\ $$$$\bigtriangleup\mathrm{27}\rightarrow\left(\mathrm{7}−\mathrm{2}\right)=\mathrm{5} \\ $$$$\therefore\bigtriangleup \Box\mathrm{6754239}=\bigtriangleup \left(\mathrm{6}+\mathrm{7}+\mathrm{5}+\mathrm{4}+\mathrm{2}+\mathrm{3}+\mathrm{9}\right) \\ $$$$=\bigtriangleup \mathrm{36}=\bigtriangleup\left(\mathrm{3}×\mathrm{6}\right) \\ $$$$=\bigtriangleup\mathrm{18}=\left(\mathrm{8}−\mathrm{1}\right)=\mathrm{7}\checkmark \\ $$

△⊚□6754239  =△⊚(6+7+5+4+2+3+9)  =△⊚36  =△(3×6)  =△18  =8−1  =7  possible ans is 7.

$$\bigtriangleup\circledcirc\Box\mathrm{6754239} \\ $$$$=\bigtriangleup\circledcirc\left(\mathrm{6}+\mathrm{7}+\mathrm{5}+\mathrm{4}+\mathrm{2}+\mathrm{3}+\mathrm{9}\right) \\ $$$$=\bigtriangleup\circledcirc\mathrm{36} \\ $$$$=\bigtriangleup\left(\mathrm{3}×\mathrm{6}\right) \\ $$$$=\bigtriangleup\mathrm{18} \\ $$$$=\mathrm{8}−\mathrm{1} \\ $$$$=\mathrm{7} \\ $$$${possible}\:{ans}\:{is}\:\mathrm{7}. \\ $$
