When x is added to each of 10, 23, 15 and 33, the sums obtained in this order are in proportion. The value of (x + 5) is:

Solution & Step-by-step Explanation

Since the numbers are in proportion after adding x : \frac{10 + x}{23 + x} = \frac{15 + x}{33 + x} Cross-multiplying to solve for x : (10 + x) (33 + x) = (15 + x) (23 + x) 330 + 43 x + x^{2} = 345 + 38 x + x^{2} 43 x - 38 x = 345 - 330 5 x = 15 ⟹ x = 3 We need to find the value of (x + 5) : Value = 3 + 5 = 8
