Amount of sand in percentage

Sample size

Note:After being dumped in the river repeatedly the sugar melts away leaving behind the insoluble sand

Generally the equation for Amount of sand content is mathematically given by

Therefore

After drying, the mass of the contents of the bag equals

Option E
