Pervez, Sunny and Ashu can each complete a piece of work alone in 30, 50 and 40 days respectively. Their daily wages are in the ratio 4 : 3 : 2. Pervez earns Rs 144 in all for completing the work alone. How much does Sunny earn in all for completing the same work alone?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Rs 180
Total earning = number of days worked × daily wage. Pervez’s total gives the value of one share of the wage ratio.
Daily wages: Pervez \(4u\), Sunny \(3u\), Ashu \(2u\)
Pervez: \(30\times4u=120u=144\), so \(u=1.2\)
Sunny: \(50\times3u=150u=150\times1.2=\) Rs 180
Sunny earns Rs 180.
