Consider the following DO statement in Fortran 77
DO 52 N = 1, 10, 3
Answer: Option
Explanation:
Do statement is executed when N = 1, 4, 7, 10, i.e., a total of 4 times.

Yes, Fortran(derived from "Formula Translation") 77 is a language.
Fortran 77 has only one loop construct, called the do-loop.
The do-loop is used for simple counting. expr1 specifies the initial value of var, expr2 is the terminating bound, and expr3 is the increment.
Here,
DO 52 N = 1, 10, 3.
So, 1 initial value.
10 terminating bound.
3 increment step.
So,
1 + 3 = 4.
4 + 3 = 7.
7 + 3 = 10.

@Swathi.
It's 4 times not 3 times.
The initial number is 1 and then 3 is added to it (we get 4) , again 3 is added to 4 (we get 7), similarly the last number we get is 10 and the loop reaches its upper limit and thus ends there. Hence, the loop executes 4 times in total.

What does 52 mean in between DO and N, it is definitely not a part of the instruction. The answer suggests the inclusion of 4 and 7, that too remains unexplained.

Number 52 is just a label in FORTRAN 77. The logic is to continue in a loop for every sum of 3 to first element i.e. 1 and end loop if number equals to 10.
