16 boys or 24 girls can construct the wall in 6 days . the number of days that 8 boys and 12 girls will take to construct ?
"explanation : 16 boys = 24 girls , 1 boy = 24 / 16 girls 1 boy = 6 / 4 girls 8 boys + 12 girls = 8 × 6 / 4 + 12 = 12 + 12 = 24 girls 6 days to complete the work answer : option c"
divide(const_1, add(multiply(12, divide(divide(const_1, 6), 24)), multiply(8, divide(divide(const_1, 6), 16))))
