Question

the weight of four boxes together 66.6 the weight of box B is 2kg less than box A and little weight of box C is 1.5kg more than box A the weight of box D is 1.5 more than box C find the weight of each box

Answer 1

Answer:

From the given data we can write

B=A−2

C=A+1.5

D=C+1.5=A+1.5+1.5=A+3

We have A+B+C+D=66.5

⇒A+A−2+A+1.5+A+3=66.5

⇒4A=64

⇒A=16

Therefore box A weighs 16kg, box B weighs 16−2=14kg, box C weighs 16+1.5=17.5kg and box D weighs 16+3=19kg

Hence A weighs 16kg

B weighs 14kg

C weighs 17.5kg

D weighs 19kg
