# Word Problem 9

**Problem 9: A glass full of milk weighs one kilogram and the glass half full of milk weighs 3/4 kilogram. What is the weight of glass ?**

**a. 1/4 kilogram b. 1/3 kilogram c. 1/8 kilogram d. 1/2 kilogram**

— general mathematics for kids –

**Solution:**

Let weight of glass

Weight of milk only (full glass)

So, total weight when glass is full of milk

But it is given that when glass is full of milk then it wieghs one kg i-e;

Now when glass is filled half with milk then ofcourse weight of milk

and total weight including glass

but it is given that when glass is filled half then weight is 3/4 kg, i-e;

subtracting eq 2 from eq 1

So, the weight of milk only (when glass is full) if half KG

But if we put this value of z in eq 1, we get;

**So, weight of glass is also half kg**
