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 ?

Options

A. 4
B. 8
C. 12
D. 16

Answer

D

Explanation

`(M_1 D_1)/( W_1) = (M_2 D_2)/( W_2)`
`rArr ( 4 xx 4)/( 4) = (8 xx 8)/( W_2)`
`therefore W_2 = (8 xx 8 xx 4)/( 16) = 16` बुनकर
