Question

Daca a =200, b=500 c cu 400 mai mare decat aa,d cu 100 mai mic decat b, afla:

a+b b+d c-a b-d c+ d-a c+d - (a+b)
​

Answer 1

a = 200

b = 500

c = 200 + 400

c = 600

d = 500 - 100

d = 400

____________

a + b = 200 + 500 = 700

b + d = 500 + 400 = 900

c - a = 600 - 200 = 400

b - d = 500 - 400 = 100

c + d - a = 600 + 400 - 200 = 1.000 - 200 = 800

c + d - ( a + b ) = 600 + 400 - ( 200 + 500 )

= 1000 - 700

= 300

Answer 2

a=200 b=500 c=400+200 c=600
