Answer : 3. "4 days"
Explanation :

Answer: C) 4 days Explanation: One day work of 6 boys and 8 girls is given as 6b + 8g = 1/10 -------->(I) ┬а One day work of 26 boys and 48 women is given as 26b + 48w = 1/2 -------->(II) ┬а Divide both sides by 2 in (I) and then multiply both sides by 5 Now we get,┬а15b + 20g = 1/4. Therefore, 15 boys and 20 girls can do the same work in 4 days.
