3 men and 4 boys can earn rs 765 in 7 days. 11 men and 13 boys can earn rs 3008 in 8 days. in what time will 7 men and 9 boys earn rs 2480?

????

total number of man days = 80*64= 5120.

From given condition total number of man days = (36*46+26*100)= 5480 man days

additional number of man days = (5480-5120) = 360

so M*D= 360

80*d= 360

D = 4.5.
