Answer: Option A
Solution(By Examveda Team)
Let 1 boy's 1 day's work = x And 1 girl's 1 day's work = y Now, (5 boys + 2 girls)'s work = 5x + 2y Given , 5x + 2y is equal to 4 times work done by a boy and a girl Thus, 5x + 2y = 4(x + y) 5x + 2y = 4x + 4y x = 2y $$\frac{{\text{x}}}{{\text{y}}} = \frac{2}{1}$$ Hence, the required ratio is 2 : 1Related Questions on Time and Work
