$$frac{M1D1}{W1}$$ = $$frac{M2D2}{W2}$$ W1=W2 = Q $$frac{18Mx30}{Q}$$ = $$frac{16Wx36}{Q}$$ M = $$frac{32}{30}$$W ....(1) Let the days required by 18 women to complete the remaining work = y days so $$frac{(15Mx9)+(18W x y)}{Q}$$ = $$frac{16Wx36}{Q}$$ ......(2) using equation 1 and 2 $$frac{(16Wx9)+(18W x y)}{Q}$$ = $$frac{16Wx36}{Q}$$ 144W + 18Wy = 576W
18Wy = 432 W y = 24 days
