women work. ...........(1)So total amount of work to be done by women = </strong><strong>1</strong><strong>8</strong><strong>X</strong><strong>1</strong><strong>4</strong><strong> =</strong><strong>2</strong><strong>5</strong><strong>2</strong><strong>

12 women + 16 women will take time = 28 women will take time

12 women + 16 women will take time = 28 women will take timetime = \dfrac{</strong><strong>w</strong><strong>o</strong><strong>r</strong><strong>k</strong><strong>}{</strong><strong>N</strong><strong>u</strong><strong>m</strong><strong>b</strong><strong>e</strong><strong>r</strong><strong> </strong><strong>o</strong><strong>f</strong><strong> </strong><strong>w</strong><strong>o</strong><strong>m</strong><strong>e</strong><strong>n</strong><strong>}
