This year, the sum of ages of the Suresh’s family members is 78....
S+R+D+T = 78 – (i)
S = R + 4 – (ii)
D = T + 2 – (iii)
S = 7T – (iv)
7T = R+4
R= 7T – 4
h+w+d+s = 78 – (i)
7T+7T-4+T+2+T = 78
16T = 80
T = 5
d = T+2 = 5+2 = 7
S = R + 4 – (ii)
D = T + 2 – (iii)
S = 7T – (iv)
7T = R+4
R= 7T – 4
h+w+d+s = 78 – (i)
7T+7T-4+T+2+T = 78
16T = 80
T = 5
d = T+2 = 5+2 = 7

This year, the sum of ages of the Suresh’s family members is 78....
's family members is 120. If Suresh's age is twice the average age of his family members, then Suresh's age is 40.
Here's how to solve it:
Let's assume that there are n family members in Suresh's family.
The sum of ages of Suresh's family members = 120
So, we can write an equation:
age of Suresh + sum of ages of other family members = 120
Let's assume that the average age of Suresh's family members is x.
So, we can write another equation:
(sum of ages of all family members) / n = x
Multiplying both sides by n, we get:
sum of ages of all family members = n * x
We know that Suresh's age is twice the average age of his family members. So,
Suresh's age = 2x
Substituting this value in the first equation, we get:
2x + sum of ages of other family members = 120
Substituting the value of sum of ages of all family members from the second equation, we get:
2x + n * x = 120
Simplifying, we get:
x = 24
So, the average age of Suresh's family members is 24.
Substituting this value in the equation for Suresh's age, we get:
Suresh's age = 2 * 24 = 40.
Therefore, Suresh's age is 40.
