[amp_mcq option1=”280″ option2=”320″ option3=”360″ option4=”400″ correct=”option3″]<\/p>\n
The correct answer is (c).<\/p>\n
Let $x$ be the number. We are given that the average of $x$, its 50% and its 25% is 210. This means that:<\/p>\n
$$\\frac{x + \\frac{1}{2}x + \\frac{1}{4}x}{3} = 210$$<\/p>\n
Simplifying, we get:<\/p>\n
$$\\frac{7}{12}x = 210$$<\/p>\n
Multiplying both sides by $\\frac{12}{7}$, we get:<\/p>\n
$$x = 360$$<\/p>\n
Therefore, the number is 360.<\/p>\n
Option (a) is incorrect because 280 is not a multiple of 7.<\/p>\n
Option (b) is incorrect because 320 is not a multiple of 7.<\/p>\n
Option (d) is incorrect because 400 is not a multiple of 7.<\/p>\n","protected":false},"excerpt":{"rendered":"
