Answer / naseera shaik
3 men = 6 boys (6 men + 2 boys) = 14 boys.
More work, More days {Direct Proportion)
More boys, Less days (Indirect Proportion)
More hours per day, Less days (Indirect Proportion)
Work 1 : 2 }
Boys 14 : 6 } :: 10 : x
Hours per day 8 : 7 }
.-. (1 X 14 X 8 X x) = (2 X 6 X 7 X 10) <=> x = (840/112) = 15/2=7*1/2
