solve this question..

Answer 1

brand A is cheaper than brand B
because Brand A 5 kg=50
1kg = 50/5
1 kg of brand A soil is 10 Rs
and Brand B 4 kg = 48
1kg =48/4
1kg of brand B soil is 12 Rs

Answer 2

soil of brand a for 5kg =$50
rate of 1kg soil of brand a=50/5=10$
rate of soil of brand b for 4kg=48$
rate of soil of brand b for 1kg=48/4=12$
so the soil which is more cheaper =12$-10$
=2$
so soil of brand a is more cheaper than soil of brand b by 2$
