2. %
3. 30% of x is 150. Percentage means divided by 100. Now, from the given direction this expression 0.30 x is equal to 150. Therefore, the value of x is 500
4. 52.52%
5. X=50
II.ANSWER THE FOLLOWING QUESTIONS
1. Now, it will divide 450.) =x=75. Therefore, the value of x is 75. This also shows that 75% of 600 is 450
2. Let say Number = X
Number increased by 18 %
=> (18/100)X = 0.18X
A number when increased by 18% gives 236
=> X + 0.18X = 236
=> 1.18X = 236
Dividing both sides by 1.18
=> X = 200
Hence 200 when increased by 18% gives 236
