Question

How many jars each holding 1.75 kg of jam can be filled from a vessel containing 100 kg of jam, and how much ramains?

Answer 1

Number of jars required for $1.75$ kg of jam $=1$

Number of jars required for $1$ kg of jam $=\frac{1}{1.75}$

Number of jars required for $100$ kg of jam $=\frac{100}{1.75}$

$=\frac{10000}{175}$

$=57\frac{1}{7}$

So, $57$ jars can be filled completely, which contains $1.75\times 57=99.75$ kg of jam.

Jam remaining in the vessel $=100-99.75=0.25$ kg
