Detailed Solution

Given,
The weight of Rahul is

5 kg

more than Sachin.
The weight of Samir is

12 kg

less than double the weight of Sachin.
Total weight of all the three = 93 kg.
Let weight of Sachin

= x kg

Then,
Weight of Rahul

= (x + 5) kg

Weight of Samir

= (2 x - 12) kg

Total weight of all

= 93 kg

That is,

\Rightarrow x + (x + 5) + (2 x - 12) = 93

\Rightarrow x + x + 5 + 2 x - 12 = 93

\Rightarrow 4 x - 7 = 93

Hence, the required equation is

4 x - 7 = 93

.
Therefore, option 1 is correct.
