Q2. Deposits in Women's Co-operative Credit Societies — Read the figures.

✍ Real-Life Application: These are actual deposit amounts from different Maharashtra districts. Reading large rupee amounts accurately is an important life skill! Always prefix with "Rupees" when reading money values.

Nashik	₹ 61,07,187	Rupees sixty-one lakh, seven thousand, one hundred and eighty-seven.

📖 Concept: Expanded Form & Place Value

✍ Key Idea: The expanded form of a number shows the place value of every digit written as an addition. If a digit is 0, its place value is 0 — it can be skipped in the expanded form.

Example: 27,65,043

TL	L	TTh	Th	H	T	U
2	7	6	5	0	4	3

✓ Expanded form: 20,00,000 + 7,00,000 + 60,000 + 5,000 + 0 + 40 + 3

Example: 95,04,506
✓ 90,00,000 + 5,00,000 + 4,000 + 500 + 6
✍ Note: The 0s in ten-thousands and tens places are simply left out from the expanded form.

Reverse: From expanded form → Number
4,00,000 + 90,000 + 200
✍ Working: TL=0, L=4, TTh=9, Th=0, H=2, T=0, U=0 → Fill missing places with 0.
✓ 4,90,200

💡 Exam Tips

⚡ Zero Skipping Rule: When writing in words, if a middle group is all zeros (like 00,000 in 50,00,000), skip it entirely. Just say "Fifty lakh"!

⚡ Expanded Form Tip: Write each digit × its place value. Zero digits contribute 0 — you may omit them from the sum.

⚡ Place Value vs Face Value: Face value of 9 in 95,04,506 is just 9. But its place value = 90,00,000!

⚠️ Common Mistakes

❌ Error: Writing "Sixty lakh and ten" as 60,10 or 60,10,000.

✔️ Correct: 60,00,010 — always fill in the missing intermediate zeros as placeholders!

❌ Error: Forgetting "Ten Lakhs" place and treating 7-digit numbers as 6-digit.

✔️ Correct: Count digits carefully from right: if there are 7 digits, the leftmost is in the Ten Lakhs place.
