Solutions — Percentage Questions 81 to 90
81. The population of a village has increased annually at the rate of 20%. If at the end of 3 years it is 19440. Then what was the population in the beginning of first year ?
Sol:
82. In a village 30% of the population is female. 80% of the female and 60% of male are married. Then what will be the % of unmarried population in the village ?
Sol:
∴ total unmarried = 6 + 28 = 34
∴ required % = \(\frac{{34}}{{100}} \times 100\)
= 34% Answer
83. The price of an article was increased by x%. Later the new price was decreased by x%. If the latest price was Rs. 1. Then what was the original price ?
Sol:
84. In the expression xy², the value of both the variables x and y are decreased by 40%. By this the value of the expression is decreased by how much ?
Sol:
∴ required % = \(\frac{{98}}{{125}} \times 100\)
= 78.4% Answer
