|
Answer» Answer: 36 Step-by-step explanation: let the number of camel is x Number of camels was seen in the forest = x/4 Number of camels had gone to the mountains = 2√x number of camels were seems on the bank of river = 15 so, total number of camels = x/4 + 2√x + 15 = x or, 2√x + 15 = 3x/4 or, 8√x + 60 = 3x or, 64x = 9x² + 3600 - 360x or, 9x² + 360x + 64x + 3600 = 0 or, 9x² + 424x + 3600 = 0 After solving with help of formula to find root of quadratic equation We get, x = 36 and 100/9 Hence, number of camels = 36 hit like if you find it useful |

|
Answer» Let the number of camel is x Number of camels was seen in the forest = x/4 Number of camels had gone to the mountains = 2√x number of camels were seems on the bank of river = 15 so, total number of camels = x/4 + 2√x + 15 = x or, 2√x + 15 = 3x/4 or, 8√x + 60 = 3x or, 64x = 9x² + 3600 - 360x or, 9x² - 360x - 64x + 3600 = 0 or, 9x² - 424x + 3600 = 0 9x² - 324x - 100x + 3600 = 0 9x(x - 36) - 100(x - 36) = 0 We get, x = 36 and 100/9 Hence, number of camels = 36 |
