Question

can anyone solve this​

Answer 1

Let the first two boxes be a and b

the next two boxes be c and d

then,

a+b = 8 -----(1)

a+c = 13 -----(2)

b+d = 8 -------(3)

c-d = 6 --------(4)

(3)+(4) => b+c = 14 -----(5)

(5)-(2) => a-b = 1 -----(6)

(6)+(1) => 2a = 9

a = 9/2

b = 7/2

c = 21/2

d = 9/2
