Work and Time Math Solution: 8(4M+6W)=10(3M+7W)  ⟹  32M+48W=30M+70W  ⟹  2M=22W  ⟹  1M=11W8(4M + 6W) = 10(3M + 7W)   ⟹  \implies⟹ 32M + 48W = 30M + 70W   ⟹  \implies⟹ 2M = 22W   ⟹  \implies⟹ 1M = 11W8(4M+6W)=10(3M+7W)⟹32M+48W=30M+70W⟹2M=22W⟹1M=11W. Total Work =(4×11+6)×8=50×8=400 woman-days= (4 ×\times× 11 + 6) ×\times× 8 = 50 ×\times× 8 = 400\ woman-days\text{woman-days}woman-days=(4×11+6)×8=50×8=400 woman-days.
