A shopkeeper bought cooking fat in 30 one kilogram packets and 20 five hundred packets. She repacked the fat in packets of 125 grams each. How many packets did she get?

Answer 1

Assuming the second purchase was in 500 g packages .... (typo)

The shopkeeper bought 30(1000) + 20(500) or
40000g , or 40 kg

He/she divided this into 40000/125 smaller packets or
320 packets of 125 g each
