Correct answer: (A) 5.55
Each term is a perfect square of a decimal: √0.0025 = 0.05, √0.25 = 0.5, √25 = 5 (the number of decimal places halves under the root). Sum = 0.05 + 0.5 + 5 = 5.55. Taking √0.0025 as 0.5 shifts the decimal point wrongly.

सही उत्तर: (A) 5.55
प्रत्येक पद किसी दशमलव का पूर्ण वर्ग है: √0.0025 = 0.05, √0.25 = 0.5, √25 = 5 (मूल के नीचे दशमलव स्थान आधे हो जाते हैं)। योग = 0.05 + 0.5 + 5 = 5.55। √0.0025 को 0.5 लेना दशमलव बिंदु की गलती है।
