Step-by-step explanation:
let weight of bag B be x kg
weight of bag A = x - 2.5
weight of bag C = x + 2.5
weight of bag D = x + 2.5 + 2
= x +4.5
A +B + C + D = 74.5
x-2.5+x+x+2.5+x+4.5=74.5
4x = 74.5-4.5
4x =70
x = 17.5
weight of bag A = 17.5-2.5
=2.5kg
weight of bag B = 17.5 kg
weight of bag C = 17.5+2.5
= 20 kg
weight of bag D = 17.5 + 4.5
= 22 kg
