12 buckets of water fill a tank when the capacity of each tank is 13.5 litres. How many buckets will be needed to fill the same tank, if the capacity of each bucket is 9 litres? Pick:	A) 15 bukets	B) 17 bukets	C) 18 bukets	D) 19 bukets	E) None of these
Explanation:   Capacity of the tank = (12*13.5)= 
<gadget id="calculator">(12*13.5)</gadget>
<output>162</output>
162 litres   Capacity of each bucket= 9 litres.   So we can get answer by dividing total capacity of tank by total capacity of bucket.   Number of buckets needed = (162/9)= 
<gadget id="calculator">(162/9)</gadget>
<output>18</output>
18 buckets   Option 18 bukets
<result>C</result>
12 buckets of water fill a tank when the capacity of each tank is 13.5 litres. How many buckets will be needed to fill the same tank, if the capacity of each bucket is 9 litres?
