Select the correct answerIn a class Rajan got the 11th rank and he was 31st from the bottom of the list of boys passed. Three boys did not take the examination and one failed. What is the total strength of the class?Options42324546
Solution
Para resolver esta pregunta, sigamos los pasos uno por uno:
- Rajan obtuvo el 11º lugar desde la parte superior.
- Rajan fue el 31º desde la parte inferior.
Esto significa que hay 30 estudiantes por debajo de Rajan.
-
Sumamos los estudiantes por encima y por debajo de Rajan, incluyendo a Rajan mismo: 10 (por encima) + 1 (Rajan) + 30 (por debajo) = 41 estudiantes que pasaron el examen.
-
Tres estudiantes no tomaron el examen y uno falló.
-
Sumamos estos estudiantes al total: 41 (que pasaron) + 3 (que no tomaron el examen) + 1 (que falló) = 45.
Por lo tanto, la fuerza total de la clase es 45.
La respuesta correcta es: 45.
