A worker has an increase of 12% in her wages per hour, but there is a drop of 10% in the number of hours worked per week. If her original weekly wages for a week of 40 hours are ₹38,400, then the percentage increase in her total weekly wages is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1.25%.
Original hourly wage = 38400/40 = 960
New hourly wage = 960 × (112.5/100) of 960) = 1080
New weekly hours = 40 × (90/100) = 36 hours
New weekly wage = 1080 × 36 = 38880
Wage difference = 38880 - 38400 = 480
Percentage increase = (480/38400) × 100 = 1.25%
