Q.

4 mat-weavers can weave 4 mats in 4 days. At the same rate, how many mats would be woven by 8 mat-weavers in 8 days?

View Answer

Correct choice: D

Explanation:

Let the required number of bottles be x.

More weavers, More mats (Direct Proportion)

More days, More mats (Direct Proportion)

Wavers 4 : 8 :: 4 : x
Days 4 : 8

∴ 4 x 4 x x = 8 x 8 x 4

⇒ x = (8 x 8 x 4)
(4 x 4)

x = 16.
