Question

Two boys and three girls can complete a task in 8 days, while eleven boys and nine girls can complete the same task in 2 days. If a boy is paid Rs. 435 per day, then find the daily wages of a girl.

• A. Rs. 420
• B. Rs. 430
• C. Rs. 425
• D. Rs. 435

Answer 1

2+3 = 5 people can complete a task in 8 days.
11+9 = 20 people can complete the same task in 2 days.
In case 2, there is an increase of 400% in the number of people and the time taken for the task to complete has reduced by 400% and the boys to girl ratio is different in both the cases implying that the efficiency of both boys and girls are equal.
Hence, they should be paid the same i.e., Rs. 435.
