Percentage Solved Examples for SSC CGL
Exam-pattern questions from the practice bank, with full solutions.
The price of sugar increases by 25%. By what percentage should a household reduce its consumption so that the expenditure remains the same?
- A.20%Correct
- B.25%
- C.15%
- D.30%
Solution
If price increases by 25%, new price = 125% of original. To keep expenditure same, new consumption = (100/125) x 100% = 80%. Reduction = 100% - 80% = 20%. Shortcut: Reduction % = (increase% / (100 + increase%)) x 100 = (25/125) x 100 = 20%.
If the salary of Ramesh is 20% more than that of Suresh, then the salary of Suresh is what percent less than that of Ramesh?
- A.16.67%Correct
- B.20%
- C.18%
- D.15%
Solution
Let Suresh's salary = Rs 100. Then Ramesh's salary = Rs 120. Difference = 120 - 100 = 20. Percentage less = (20/120) x 100 = 16.67%. Shortcut: If A is x% more than B, then B is (x/(100+x)) x 100% less than A = (20/120) x 100 = 16.67%.
The population of a town increases by 10% in the first year and decreases by 10% in the second year. If the present population is 10000, what will be the population after 2 years?
- A.10000
- B.9900Correct
- C.9800
- D.10100
Solution
After 1st year: 10000 x 110/100 = 11000. After 2nd year: 11000 x 90/100 = 9900. Alternatively, net effect = -1% (using successive change formula: 10 - 10 - (10x10)/100 = -1%). 10000 x 99/100 = 9900.
