Question

the total weight of 4 boxes is 74.5kg. The weight of box A is 2.5kg less than box B and weight of box C is 2.5 kg more than box B. The weight of box D is 2kg more than box C. Find the weight of each box.

Answer 1

Let the weight of box A be x kg
Then weight of box B is (2.5+x)kg
Weight of box C is (5+x)kg
N weight of box D is (7+x)kg
Now, the total weight of the box is
x+(2.5+x)+(5+x)+(7+x)=74.5
4x + 14.5 = 74.5
4x= 74.5-14.5
X= 60/4
x= 15
So the value of x is 15 and weight of box A is 15kg
N box B is (2.5+x)= (2.5+15)= 17.5kg
Box C is (5+x)=(5+15)=20kg
Box D is (7+x)=(7+15)=22kg

Answer 2

Answer:

a = 15 kg

b=17 kg

c=20kg

d= 22 kg
