Question

In Bilaspur village, 12 men and 18 boys completed
construction of a primary health centre in 60 days,
by working for 7.5 hours a day. Subsequently the
residents of the neighbouring Harigarh village also
decided to construct a primary health centre in their
locality, which would be twice the size of the facility
built in Bilaspur. If a man is able to perform the
work equal to the same done by 2 boys, then how
many boys will be required to help 21 men to
complete the work in Harigarh in 50 days, working 9
hours a day?​
