Question

3. 87 kg of potatoes are distributed in two boxes. One box weighs 11 kg less than
the other one. The lighter box contains how many kilograms of potatoes?​

Answer 1

Answer:

I think your question has some error

but I see below

suppose 2 boxes have total weight 40 kg

and one is 10 kg less weight of potatoes

let's x and Y 2 boxes

so X+Y=40 equation 1

given X has 10 kg less than Y

so X=Y-10

now

put X = Y-10 in 1

Y-10+Y=40

2Y=40+10

Y=25

and X =25-10=15

hope it will helpful
