Question

solve it fast plz .....

Answer 1

Take four different boxes as a,b,c,d

a + b = 8. (1)
a + c = 13. (2)
c - d = 6. (3)
b + d = 8. (4)


by adding 3 & 4 equations
b + c = 14

by adding 1 and 2 equations
2a + b + c = 21
2a + 14 = 21
a = 7/2

by substituting a in equation 1
B = 9/2

by substituting b in equation 4
d = 7/2

by substituting d in equation 3
c = 19/2
