Each large box weighs 15 kilograms and each small box weighs 13.5 kilograms.
Step-by-step explanation:
Let,
Weight of large box = x
Weight of small box = y
According to given statement;
5x+2y=102 Eqn 1
3x+8y=153 Eqn 2
Multiyplying Eqn 1 by 4

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 17

Putting x=15 in Eqn 2

Dividing both sides by 8

Each large box weighs 15 kilograms and each small box weighs 13.5 kilograms.
