The establishment offers a diverse selection comprising four distinct models: A, B, C, and D, and their selling prices are Rs. 10,000, Rs. 16,000, Rs. 20,000, and Rs. 25,000 respectively.For every sale of a phone of model A, B, C, and D, Ramesh receives a commission of 5%, 8%, 10%, and 10% on selling price respectively.

Solution

Para resolver este problema, sigamos los siguientes pasos:

  1. Determinar el número de teléfonos vendidos por Ramesh y Suresh:

    • Sea R R el número total de teléfonos vendidos por Ramesh.
    • Sea S S el número total de teléfonos vendidos por Suresh.
    • Dado que juntos vendieron 53 teléfonos y Ramesh vendió 11 más que Suresh: R+S=53 R + S = 53 R=S+11 R = S + 11
  2. Resolver el sistema de ecuaciones: (S+11)+S=53 (S + 11) + S = 53 2S+11=53 2S + 11 = 53 2S=42 2S = 42 S=21 S = 21 R=S+11=21+11=32 R = S + 11 = 21 + 11 = 32

    Entonces, Ramesh vendió 32 teléfonos y Suresh vendió 21 teléfonos.

  3. Determinar la cantidad de cada tipo de teléfono vendido por Ramesh y Suresh:

    • Para Ramesh:

      • Teléfonos tipo A y D en igual número.
      • Teléfonos tipo B y C en igual número.
      • Ratios de ventas:
        • A: 2/5
        • B: 4/5
        • C: 3/5
        • D: 1/5

      Sea x x el número de teléfonos tipo A vendidos por Ramesh: Teleˊfonos tipo A=x \text{Teléfonos tipo A} = x Teleˊfonos tipo D=x \text{Teléfonos tipo D} = x Teleˊfonos tipo B=y \text{Teléfonos tipo B} = y Teleˊfonos tipo C=y \text{Teléfonos tipo C} = y

      Dado que x+x+y+y=32 x + x + y + y = 32 : 2x+2y=32 2x + 2y = 32 x+y=16 x + y = 16

    • Para Suresh:

      • Ratios de ventas:
        • A: 3/5
        • B: 1/5
        • C: 2/5
        • D: 1/5

      Sea z z el número de teléfonos tipo A vendidos por Suresh: Teleˊfonos tipo A=z \text{Teléfonos tipo A} = z Teleˊfonos tipo D=w \text{Teléfonos tipo D} = w Teleˊfonos tipo B=v \text{Teléfonos tipo B} = v Teleˊfonos tipo C=u \text{Teléfonos tipo C} = u

      Dado que z+w+v+u=21 z + w + v + u = 21 : 35z+15w+25u+15v=21 \frac{3}{5}z + \frac{1}{5}w + \frac{2}{5}u + \frac{1}{5}v = 21

  4. Calcular la comisión de Ramesh en febrero:

    • Comisión por tipo A: 0.05×10000×x 0.05 \times 10000 \times x
    • Comisión por tipo B: 0.08×16000×y 0.08 \times 16000 \times y
    • Comisión por tipo C: 0.10×20000×y 0.10 \times 20000 \times y
    • Comisión por tipo D: 0.10×25000×x 0.10 \times 25000 \times x

    Total comisión de Ramesh: 0.05×10000×x+0.08×16000×y+0.10×20000×y+0.10×25000×x 0.05 \times 10000 \times x + 0.08 \times 16000 \times y + 0.10 \times 20000 \times y + 0.10 \times 25000 \times x

  5. Calcular la comisión de Ramesh en marzo:

    • Para obtener al menos un 50% más de comisión en teléfonos tipo A: 1.5×(0.05×10000×x)=0.075×10000×x 1.5 \times (0.05 \times 10000 \times x) = 0.075 \times 10000 \times x

    • Necesitamos calcular cuántos teléfonos adicionales tipo A necesita vender para alcanzar esta comisión.

    Si x x es el número de teléfonos tipo A vendidos en febrero, entonces en marzo necesita vender x+n x + n teléfonos tipo A para obtener al menos un 50% más de comisión.

    0.075×10000×(x+n)0.05×10000×x×1.5 0.075 \times 10000 \times (x + n) \geq 0.05 \times 10000 \times x \times 1.5

    Simplificando: 0.075×(x+n)0.075×x 0.075 \times (x + n) \geq 0.075 \times x

    x+n1.5x x + n \geq 1.5x

    n0.5x n \geq 0.5x

    Dado que x=8 x = 8 (de la ecuación x+y=16 x + y = 16 y x=8 x = 8 ), entonces: n0.5×8 n \geq 0.5 \times 8

    n4 n \geq 4

    Por lo tanto, la respuesta es: 4 \boxed{4}
