  1. 1. (a) 1,00,000 — One lakh = 1,00,000 (hundred thousand).
  2. 2. (b) 100 — 1 crore = 100 lakh.
  3. 3. (c) 1 million — Ten lakh = one million.
  4. 4. (d) 6,00,000 — 6 is in the lakh place: 6,00,000.
  5. 5. One hundred lakh make a crore.
  6. 6. Three lakh (3,00,000).
  7. 7. Both systems use commas to group digits, but they group differently. The Indian system places the first comma after three digits (thousands) and then after every two digits, giving the places ones, thousands, lakhs and crores — for example, 23,45,678. The international system places a comma after every three digits, giving ones, thousands and millions — the same number is written 2,345,678. The link between them is that ten lakh equals one million and one crore equals ten million, so the same quantity can be read in either system.
