Question

If 87.5kg of flour remains with a shopkeeper in the evening after he sells of 30% of the flour that he had in the morning, how much flour did the shopkeeper start with in the morning?​

Answer 1

Let the total amount of flour be x in the morning.

Let the flour used =y

So, x-y=87.5 (1)

And y/x ×100=30%

y=30/100×x

So, x-30x/100=87.5

70x/100=87.5

70x=8750

x=125 kg of flour.

Answer 2

Answer:

given,

30% sold

70% unsold

Step-by-step explanation:

87.5×30÷70=37.5

therefore total sell=37.5

total flour =37.5+87.5=125

total flour =125
