Answer:

#x = "Rs " 15,000#

Explanation:

We can treat percentage questions as an equation or use direct proportion.

Method 1 . "11% of something (x) is 1650"

#x# has to be an amount much bigger than 1650.

#11/100 xx x = 1650 larr # solve for #x#

#x = 1650 xx 100/11#

#x = "Rs " 15,000#

Method 2 : Compare the amounts with the percents.

"If 11% is 1650. how much is 100%?"

#11/100 = 1650/x larr # cross-multiply

#x = (1650 xx100)/11#

#x = "Rs " 15,000#

Check:

#11/100 xx 15000 = 1650#
