Step-by-step explanation:
question number B
the LCM of times
is 60 minutes
=11 am after 12pm
a) Two ropes of 12m and 16m long are to be cut down into small pieces of equal length . What will be the maximum length of each piece??
Answer = take the HCF of the length of the 2 rope's = HCF of 12- 2×2×3
HCF of 16- 2×2×2×2.
so now the common factors of 12,16 are 2
so the HCF of 12,16 is 2 × 2 = 4
• now the maximum length of each piece = 4m
b) Three bells ring at intervals of 15 , 30 , 30 minutes If they ring together at 11 am . what time will they next ring together??
Answer = first bell rings at the time of - 15 min
second bell rings at the time of - 30 min
3rd bell rings at the time of = 30 min
total time taken - 15min+30min+30min = 1hr 15 min
if they ring together at 11am at what time they will ring next?? - 60+60+15 = 12 : 15
the next bell rings at - 12:15 pm
c) Find the greatest number that can exactly divide 147,161,210.
answer - to find the greatest number that can divide these numbers-
• take out the HCF of these numbers and it is 7
•147÷7 = 21
•161÷7 = 23
•210÷7 = 30
I think the number is 7
d) A chef has two recipes.In his recipe A he requires 105 ml of oil and in his recipe B he requires 135 ml of oil.What is the largest measure he can use for both the recipe??
Answer- required amount of oil in recipe A- 105 ml.
required amount of oil in recipe B - 135ml.
Amount of oil required for both the recipe=105+135/5 = 132ml
e) What is the least number of apples a teacher should so that when she distributes equal numbers of them to her 10,15,25 students,no apple is left??
answer= number is students = 10,15,25 = 10+15+25= 50
The number is apples that is distributed equally- 50/2 = 25
so no apples are left bcoz all are distributed equally to all the 50 students
(check out if the answer is right!!)
f) A shopkeeper sold the mathematics book for rupees 120 on Monday and rupees 64 on Tuesday. What can be the maximum price of each book??
answer= amount of the book he sold on Monday= 130rupees
amount of the book he sold on Tuesday= 64rupees
the maximum price of each book maybe = 120-64= 56 , 56 +64 = 120
HOPE IT HELPS..!! CHECK OUT IF IS ITS RIGHT OR WRONG!!
THANK YOU!!!
