Solution

Para resolver esta pregunta, sigamos los pasos uno por uno:

  1. Shyam está en la posición 15 desde el extremo izquierdo.
  2. Ram está en la posición 11 a la izquierda de Shyam.
  3. Entonces, la posición de Ram desde el extremo izquierdo es 15−11=415 - 11 = 4.

Ahora, necesitamos encontrar la posición de Ram desde el extremo derecho.

  1. Harsh está en la posición 20 desde el extremo derecho.
  2. No se nos da la longitud total de la fila, pero podemos deducirla usando la información de Harsh y Shyam.
  3. La posición de Shyam desde el extremo derecho se puede calcular si conocemos la longitud total de la fila. Llamemos a la longitud total de la fila LL.
  4. La posición de Shyam desde el extremo derecho es L−15+1L - 15 + 1.
  5. Sabemos que Harsh está en la posición 20 desde el extremo derecho, así que L−15+1=20L - 15 + 1 = 20.
  6. Resolviendo para LL, obtenemos L−14=20L - 14 = 20, por lo tanto, L=34L = 34.

Finalmente, calculemos la posición de Ram desde el extremo derecho:

  1. La posición de Ram desde el extremo izquierdo es 4.
  2. Entonces, la posición de Ram desde el extremo derecho es L−4+1=34−4+1=31L - 4 + 1 = 34 - 4 + 1 = 31.

Por lo tanto, la posición de Ram desde el extremo derecho de la fila es 31. Sin embargo, ninguna de las opciones proporcionadas (50, 51, 49, None) coincide con 31. Por lo tanto, la respuesta correcta es "None".
