If the ratio is 1 : x : 5 and the sum is 11, then x =

Correct Answer: 5

In the ratio 1 : x : 5, the sum of all parts is given as 11. Therefore, we form the equation: 1 + x + 5 = 11. Adding the known values gives 6 + x = 11. Subtracting 6 from both sides results in x = 5. Ratio questions are commonly asked in mathematics and aptitude tests because they assess logical thinking and basic algebraic skills. The key is to convert the ratio statement into an equation and solve for the unknown value. Such questions are frequently included in competitive examinations like PPSC, FPSC, NTS, and other recruitment tests.
