Of the following numbers which is the greatest? Which is the smallest? 38051425, 30040700, 67205602
Greatest = 67205602, Smallest = 30040700
Idea: Compare digits from the left (highest place value) — crores, then ten-lakhs, and so on.
Step 1: Look at the crore (10,000,000) place.
6 > 3, so 67205602 is the greatest.
Step 2: Find the smallest among the remaining two (their crore digits are equal).
Compare the next place: ten-lakh (1,000,000) place.
0 < 8, so 30040700 is the smallest.
Conclusion: Greatest = 67205602; Smallest = 30040700.
