Explanation:
It is given that a man is able to perform the work equal to the same done by 2 boys. Hence, we can assume that In Bilaspur village 21= (12+18/2) men completed construction of a primary health center in 60 days, by working for 7.5 hours a day.
Hence, total men hours required to completed the primary health center in Bilaspur = 7.5*21*60 = 9450.
Let us assume that 'n' be the number of boys required to help 21 men to complete the work in Harigarh in 50 days by working 9 hours a day.
Therefore, we can say that
2*9450 = 50*9*(21+t/2)
42 = 21+t/2
t = 42
Hence, option D is the correct answer.
