ans is 75 days
15m=10w
m=10w/15;w=15m/10
5men and 4 women= 5m+(15*4/10)m = 11men
11men * x days = 15men * 55 days

solve this problem using M1*D1=M2*D2 formulae
first convert women to men
let given 15m===10m
? ===04w
by cross multiplication we get 4 women==6men
so by adding 5men+6men=11men

apply the formulae
M1*D1=M2*D2
15*55=11*D2
D2=75

Given 15 men or 10 women.

then 15men=10women => 3men=2women
Now, 5 men +2(3) men=11men
by work time men days formula
15 * 55 = 11*x
