The given table shows the production of units of different products in different months.

Y’s total production is what percentage of Z’s total production?

Correct option is C

​Solution:​

According to the question,

Total production of product Y = March + June + September + December 

=> 18 + 13 + 17 + 8 = 56

Total production of product Z = March + June + September + December 

=> 15 + 18 + 12 + 19 = 64

Now,

=> P = $$\frac{56}{64} × 100$$​​

=> P = 0.875% × 100 = 87.5%

∴ Y's total production is 87.5% of Z's total production.
