8 men, 10 women and 12 young boys, working together, earned ₹3760. If the daily wages of a man, a woman and a boy are in the ratio 2 : 3 : 4, the daily wages of 2 men, 3 women and one young boy are:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → ₹680
Write the daily wages in the given ratio as 2k, 3k and 4k, and take the ₹3760 as the earnings of one day, the period the daily wages are for.
Earnings of the whole group: \(8\times2k+10\times3k+12\times4k=16k+30k+48k=94k\)
\(94k=3760\), so \(k=40\)
2 men, 3 women and 1 boy: \(2\times2k+3\times3k+1\times4k=17k=17\times40=680\)
