Answer :
- To determine how many minutes there are in 4 hours, you multiply the number of hours by the number of minutes in one hour.\n\n [tex]4 \text{ hours} \times 60 \text{ minutes/hour} = 240 \text{ minutes}[/tex]\n\n2. To rewrite the numbers 560, 735, 230, and 239 in descending order, you arrange them from highest to lowest. So, the order will be: 735, 560, 239, 230.\n\n3. June has 30 days and October has 31 days. So, take away the number of days in June from October:\n\n [tex]31 - 30 = 1[/tex]\n\n4. To find how many 50 paisa coins make up ₹9.50, you first convert the rupees into paisa. ₹9.50 is the same as 950 paisa. Since each coin is worth 50 paisa:\n [tex]\frac{950}{50} = 19\text{ coins}[/tex]\n\n5. To solve [tex]7 \times (5 \times 5)[/tex], first calculate the expression inside the parentheses:\n [tex]5 \times 5 = 25[/tex]\n Then multiply by 7:\n [tex]7 \times 25 = 175[/tex]\n\n6. For the calculation, from [tex]9 \times 5[/tex] take away [tex]8 \times 4[/tex]:\n [tex]9 \times 5 = 45[/tex] \n [tex]8 \times 4 = 32[/tex]\n [tex]45 - 32 = 13[/tex]\n\n7. In the number 7605, the digit in the hundreds place is 6.\n\n8. The smallest 4-digit numeral is 1000. Adding 1 to find the successor, we get 1001.\n\n9. The number 4809 is one less than 4810.\n\n10. Adding 100 more to 5785 gives:\n [tex]5785 + 100 = 5885[/tex]\n\n11. At half past seven, the minute hand will be on 6 on the clock, which represents 30 minutes past the hour.\n\n12. Adding the sum of 15 and 45 to 60:\n [tex]15 + 45 = 60[/tex] \n [tex]60 + 60 = 120[/tex]
