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?
Answer: Option
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.

If 4 are weaving 4 mats in 4 days means 1 mat by 1 person then why not 8 men are weaving 8 mats in 8 days.

4 mate weavers 4 days 4 mate. Which simply tells us that 4 mate weavers can make 1 mate/day. If mate weavers are 8 then 2 mates per day. So for 8 days 16 mats.

It's too much simple.
Here let x is a work.
Chain Rule: (M1*D1)/W1 = (M2*D2)/W2.
M-men or workers.
D-Days or Time.
W-Works.
= (4*4)/4 = (8*8)/x.
==> x = 16.

4 weavers can weave 4 mats in 4 days.
In one day one weaver weaves 1/4 of a mart at the same rate.
Then 8 weavers weave 1/4 x 8 = 2 mats in one day.
There fore in 8 days 8 weavers weave 8 x 2 =16 mats.
In one day one weaver weaves 1/4 of a mart at the same rate.
Then 8 weavers weave 1/4 x 8 = 2 mats in one day.
There fore in 8 days 8 weavers weave 8 x 2 =16 mats.

(IN 4 DAYS)
4 WEAVERS CAN WEAVE 4 MATS
=>(1 WEAVER-1 MAT)--------(A)
FROM (A): 8 WEAVERS-8 MATS
SO 8 WEAVERS CAN WEAVE 8 MATS IN 4 DAYS.
IF DAYS ARE DOUBLE, MATS WILL ALSO DOUBLE.(SINCE SAME RATE OF WORK AND NO CHANE IN WEAVERS)
=>8 WEAVERS CAN WEAVE 16 MATS IN 8 DAYS.
4 WEAVERS CAN WEAVE 4 MATS
=>(1 WEAVER-1 MAT)--------(A)
FROM (A): 8 WEAVERS-8 MATS
SO 8 WEAVERS CAN WEAVE 8 MATS IN 4 DAYS.
IF DAYS ARE DOUBLE, MATS WILL ALSO DOUBLE.(SINCE SAME RATE OF WORK AND NO CHANE IN WEAVERS)
=>8 WEAVERS CAN WEAVE 16 MATS IN 8 DAYS.

Consider this
4 mats in 4 days by 4 people
Therefore each person weaves 1 mat in 4 days
If there are 8 mat weavers and 8 days, each mat weaver can weave 2 mats in 8 days (1mat/4 days)
Since there are 8 mat weavers : 8weavers * 2 mats = 16 mats !
4 mats in 4 days by 4 people
Therefore each person weaves 1 mat in 4 days
If there are 8 mat weavers and 8 days, each mat weaver can weave 2 mats in 8 days (1mat/4 days)
Since there are 8 mat weavers : 8weavers * 2 mats = 16 mats !

4 4 4
8 x 8.if ..
x = 8*8*4/4*4
= 16
see...if no. of mats inc. then no. days also inc.(DIRECT)
and if no. of people inc. then no. of days also inc.(DIRECT)
4 4 4
8 x 8.if ..
x = 8*8*4/4*4
