Question

Кянан выше Рамиза на 5см,Сардар выше Кянана на 3 см.В сумме рост троих 385.Какой рост у Сардара?

Answer 1

Пусть рост Сардара х см, тогда рост Кянана х-3 см, а рост Рамиза х-3-5=х-8 см. Составим уравнение:

х+х-3+х-8=385

3х=396

х=132.

Ответ: 132 см.

Answer 2

Calculation of Sardar's Height

To find out Sardar's height, let's break down the given information step by step:

1. Kyanan is 5 cm taller than Ramiz. 2. Sardar is 3 cm taller than Kyanan. 3. The sum of their heights is 385 cm.

Let's assign variables to their heights: - Ramiz's height = R cm - Kyanan's height = K cm - Sardar's height = S cm

Based on the given information, we can write the following equations:

1. Kyanan's height is 5 cm taller than Ramiz's height: - K = R + 5

2. Sardar's height is 3 cm taller than Kyanan's height: - S = K + 3

3. The sum of their heights is 385 cm: - R + K + S = 385

Now, let's solve these equations to find Sardar's height.

Substituting the value of K from equation 1 into equation 2: - S = (R + 5) + 3 - S = R + 8

Substituting the values of R and S into equation 3: - R + (R + 5) + (R + 8) = 385 - 3R + 13 = 385 - 3R = 385 - 13 - 3R = 372 - R = 372 / 3 - R = 124

Now that we have found Ramiz's height, we can substitute this value back into equation 1 to find Kyanan's height: - K = R + 5 - K = 124 + 5 - K = 129

Finally, we can substitute the value of K into equation 2 to find Sardar's height: - S = K + 3 - S = 129 + 3 - S = 132

Therefore, Sardar's height is 132 cm.
