Correct answer: (D) 7
Let the number added be x. For 2+x, 3+x, 11+x, 13+x to be in proportion, (2+x)/(3+x) = (11+x)/(13+x). Cross-multiplying gives 26+15x = 33+14x, so x = 7.

सही उत्तर: (D) 7
मान लीजिए जोड़ी जाने वाली संख्या x है। 2+x, 3+x, 11+x, 13+x के समानुपाती होने के लिए (2+x)/(3+x) = (11+x)/(13+x)। हल करने पर 26+15x = 33+14x, अतः x = 7 प्राप्त होता है।
