Question

the mean weight of 11 players of a cricket team is 76 kg .the mean weight of the team including two substitutes is 75 kg .find the total weight of two substitute players .​

Answer 1

WEIGHT OF 2 SUBSTITUTE PLAYER IS 139 KG

Step-by-step explanation:

Mean weight= Total weight/Total number of players

Total weight of 11 players= 76×11

Total weight of 13 players(2 substitiute) = 75×13

Weight of 2 substitute players= 75×13- 76×11

                                                 =139

Answer 2

The total weight of two substitute players is 139.

Step-by-step explanation:

Since we have given that

Number of players = 11

Mean weight = 76 kg

So, sum of observations would be

$\dfrac{\text{Sum of observations}}{\text{Number of observations}}=Mean\\\\\dfrac{\text{Sum of observations}}{11}=76\\\\\text{Sum of observations}=76\times 11=836$

Mean weight of team including two substitute = 75 kg.

So, it becomes now,

$\dfrac{\text{Sum of observations}}{\text{Number of observations}}=Mean\\\\\dfrac{\text{Sum of observations}}{13}=75\\\\\text{Sum of observations}=75\times 13=975$

So, Total weight of two substitutes would be

$975-836=139$

Hence, the total weight of two substitute players is 139.
