25 : 81 :: 36 : ?
Detailed Solution & Logic
Correct Answer:
121 / 121
25 = $5^2$ and 81 = $9^2$.
The base increases by 4: $5 \rightarrow 9$.
Similarly, 36 = $6^2$.
Increasing the base by 5 gives $11^2 = 121$.
व्याख्या:
25 = $5^2$ तथा 81 = $9^2$।
आधार (Base) में 4 की वृद्धि हुई है: $5 \rightarrow 9$।
इसी प्रकार, 36 = $6^2$।
आधार में 5 की वृद्धि करने पर $11^2 = 121$ प्राप्त होता है।
