Answers & Comments
Answer:
Sure, here are the answers to the math questions you provided:
1. To find how much money the school received, we can multiply the number of students by the admission fee each student paid:
Money received = Number of students * Admission fee per student
Money received = 420 * Rs. 15625
Money received = Rs. 6,56,25,000
2. To find how much the woman earns in a year, we can multiply her monthly salary by 12 (the number of months in a year):
Annual earnings = Monthly salary * 12
Annual earnings = Rs. 1,35,726 * 12
Annual earnings = Rs. 16,28,712
3. The number of apples sold to the bakery can be found by subtracting the number of apples returned from the total number sold:
Apples sold to bakery = Total apples sold - Apples returned
Apples sold to bakery = 65,489 - 45,678
Apples sold to bakery = 19,811
4. To find the total number of eggs in 368 buckets, we can multiply the number of eggs in each bucket by the number of buckets:
Total eggs = Number of buckets * Eggs per bucket
Total eggs = 368 * 5,765
Total eggs = 21,18,320
5. To share the candies equally among 140 friends, we can divide the total number of candies by the number of friends:
Candies per friend = Total candies / Number of friends
Candies per friend = 1,28,800 / 140
Candies per friend = 920
6. The number of valid votes can be found by subtracting the number of invalid votes from the total number of votes:
Valid votes = Total votes - Invalid votes
Valid votes = 2,80,732 - 3,463
Valid votes = 2,77,269
7. Using integer concept, we can simplify the expression as follows:
45 + 67 - (-89) = 45 + 67 + 89 (since double negative becomes positive)
= 201
8. The factors of:
a) 28: 1, 2, 4, 7, 14, 28
b) 30: 1, 2, 3, 5, 6, 10, 15, 30
c) 54: 1, 2, 3, 6, 9, 18, 27, 54
Hope that helps!
