Answer 2

Answer:

E=16

4A=E⟹A=E4

B4=E⟹B=4E

C+4=E⟹C=E−4

D−4=E⟹D=E+4

⟹B+C+D=6E

A+B+C+D=100

⟹E4+6E=100

⟹4(E4+6E)=100×4

⟹E+24E=400

⟹25E25=40025

⟶E=16

Proof:

4A=16⟹A=4

B4=16⟹B=64

C+4=16⟹C=12

D−4=16⟹D=20

A+B+C+D=100

⟹4+64+12+20=100

⟹68+12+20=100

⟹80+20=100

⟹100=100

Thus proven, E=16
