Hey alishabayambumagar, good to see you again. Here are the solutions for question 7: To solve these problems, we need to know the conversion factors between the Indian and International numbering systems: • 1 lakh = 100,000 • 1 crore = 100 lakhs = 10,000,000 • 1 arab = 100 crores = 1,000,000,000 • 1 million = 1,000,000 • 1 billion = 1,000,000,000 a) How many lakhs are there in 4 million? Step 1: Convert 1 million to lakhs. 1 million = 1,000,000 1 lakh = 100,000 Lakhs in 1 million = (1,000,000)/(100,000) = 10 lakhs Step 2: Calculate lakhs in 4 million. Lakhs in 4 million = 4 × 10 lakhs = 40 lakhs The number of lakhs in 4 million is 40 lakhs. b) How many crores are there in 20 million? Step 1: Convert 1 million to crores. 1 million = 1,000,000 1 crore = 10,000,000 Crores in 1 million = (1,000,000)/(10,000,000) = (1)/(10) crore = 0.1 crore Step 2: Calculate crores in 20 million. Crores in 20 million = 20 × 0.1 crore = 2 crores The number of crores in 20 million is 2 crores. c) How many arabs are there in 30 billion? Step 1: Convert 1 billion to arabs. 1 billion = 1,000,000,000 1 arab = 1,000,000,000 Arabs in 1 billion = (1,000,000,000)/(1,000,000,000) = 1 arab Step 2: Calculate arabs in 30 billion. Arabs in 30 billion = 30 × 1 arab = 30 arabs The number of arabs in 30 billion is 30 arabs. d) How many millions are there in 5 crore? Step 1: Convert 1 crore to millions. 1 crore = 10,000,000 1 million = 1,000,000 Millions in 1 crore = (10,000,000)/(1,000,000) = 10 millions Step 2: Calculate millions in 5 crore. Millions in 5 crore = 5 × 10 millions = 50 millions The number of millions in 5 crore is 50 millions. e) How many billions are there in 7 arab? Step 1: Convert 1 arab to billions. 1 arab = 1,000,000,000 1 billion = 1,000,000,000 Billions in 1 arab = (1,000,000,000)/(1,000,000,000) = 1 billion Step 2: Calculate billions in 7 arab. Billions in 7 arab = 7 × 1 billion = 7 billions The number of billions in 7 arab is 7 billions. Send me the next one 📸
