Verified Answer
A family has two children along with their parents. The average of the...
We know that – Average x Number of people = Total.
Average of weight of two children and their mother (i.e. total 3 members) = 50. So, the sum of the weight of two children and mother = C1 + C2 + M = 50 × 3 = 150 ... (1) (where C1 and C2 are the weights of two children and M is the weight of the Mother)
Again if the weight of the Father is F, we have C1 + C2 + F = 52 × 3 = 156 ... (2)
Now it is given that the weight of the father = F = 60.
By putting this value in equation (2), we have C1 + C2 = 156 - 60 = 96.
Again by using equation (1) we have M = 150 - 96 = 54 kg.
(If you do not want to solve this way, you can always reverse check using options also, in such questions. Since option (4) was correct, you will need to check 3 options at least).

Average = children +father/3
52 = children +60/3
52*3= children+6
156-60= children
children=96 kg

96+mother/3= 50
96+ mother =150
mother = 150-96
mother = 54 kg

A family has two children along with their parents. The average of the...
Given:
- A family has two children along with their parents.
- Average weight of the children and their mother is 50 kg.
- Average weight of the children and their father is 52 kg.
- Weight of the father is 60 kg.

To find:
- Weight of the mother.

Solution:

Let's assume the weight of the mother as M and the weight of the two children as C1 and C2.

1. Average weight of the children and their mother is 50 kg:
- (C1 + C2 + M) / 3 = 50 kg
- C1 + C2 + M = 150 kg

2. Average weight of the children and their father is 52 kg:
- (C1 + C2 + 60) / 3 = 52 kg
- C1 + C2 + 60 = 156 kg

Now, let's solve the above two equations simultaneously to find the values of C1, C2, and M.

Subtracting equation 1 from equation 2:
(C1 + C2 + 60) - (C1 + C2 + M) = 156 - 150
C1 + C2 + 60 - C1 - C2 - M = 6
60 - M = 6
-M = 6 - 60
-M = -54
M = 54 kg

Therefore, the weight of the mother is 54 kg.

Hence, the correct answer is option D) 54 kg.
