Question

27 birds out of the 45 lay eggs .What per cent of birds do not lay eggs ? options 60% , 40% ,25% , 75%​

Answer 1

60 % of them lay eggs

Answer 2

40% percent of birds do not lay eggs. Second option is correct

Step-by-step explanation:

Given data

• Total number of birds = 45

        Number of birds which lay eggs = 27

• Number of birds which do not lay eggs = Total number of birds -Number of birds which lay eggs

        Number of birds which do not lay eggs = 45 - 27 = 18

• $\mathbf{\textrm{Percentage of birds which do not lay eggs }=\frac{\textrm{Number of birds which do not lay eggs}}{\textrm{Total number of birds}}\times 100}$

        $\mathbf{\textrm{Percentage of birds which do not lay eggs }=\frac{18}{45}\times 100}$

        $\mathbf{\textrm{Percentage of birds which do not lay eggs }=\frac{2}{5}\times 100}$

• On solving, we get

        Percent of birds do not lay eggs = 40%
