Question
Quantity I: A student multiplied a number by 3/5 instead
of 5/3. What is the % error in the calculation? Quantity II: The population of a town is 2,34,000. 4/9 of them are males and rest are females. If 30% of males are married and number of married females is 2.5 times of married males. Find the percent of married females out of total females in the town?Solution
Quantity II: Number of males = 4/9× 2,34,000 = 1,04,000 Number of females = 2,34,000 – 1,04,000 = 1,30,000 Number of married males = 30/100×1,04,000 = 31,200 Number of married females = 31,200 x 2.5 = 78,000 ∴ Required percent = (78000 ×100)/130000 = 60% Hence, Quantity I > Quantity II
