Question

Shobhit bought 300 litres of milk at rs.19 per litre. he added 200 litres of water to it and sold 400 litres of this milk at rs.20 per litre. to the rest, he added 10 litres more water and then sold it for rs.15 per litre. if he used mineral water that costs rs.10 per litre, then the total money earned by shobhit is?

Answer 1

Shobhit bought litres = 500
He sold = 400 litres
He sold litres and it's cost is rs.20 per litre = 200
It's cost is 2000
He sold litres and it's cost is rs.15 per litre = 100
It's cost is 1500
He sold litres and it's cost is rs.10 per litre = 100
It's cost is 1000
Total sold = 2000 + 1500 + 1000
= 4500
This is the solution of your question. I hope that it will help you.

Answer 2

Answer:= 1,850

Step-by-step explanation:

Shobhit bought 300 litres of milk at Rs.19 = ( 300x19 = 5700) expenditure1

added 200 litres water.(total 500 litres)

sold 400 litres milk Rs.20/lit = ( 400x20 = 8000) gain1

remaining (500-400) =100litres

add 10 litres  water (100+10) to it and sold Rs.15/lit=(110x15 = 1650) gain2

total added 200+10 litres of mineral water which cost Rs.10/lit=

( 210x10 = 2100) expenditure2

money earned = Gain - Expenditure==>(gain1+gain2 - exp1 -exp2)

                                                               (8000+1650 - 5700 - 2100)

                         = 1,850
