books dealing with cleanliness,in english,hindi and sociology,have to be stacked in such a way that all books are stored topicwise and height of each stack is the same.the number of english books is 240,number of hindi books is 96 and the number of sociology books is 336. assuming that the books are of same thickness,find the number of stacks of each books? which mathematical concept is used in this problem? which good habit is discussed in this problem?
Find the HCF of 81 and 237 and express it as a linear combination of 81 and 237
to find the HCF of 657 and 963, we will use Euclid's division Lemma,
963 = 657*1+306
since the remainder is not equal to zero, we will again apply Euclid's division Lemma
657 = 306*2+ 45
306 = 45*6 + 36
45 = 36*1 +9
36 = 9*4 + 0
now we get remainder as 0 , thus the HCF of 963 and 657 is 9.
9 = 657 x + 963 x -15
1620 x = 9+15 = 24
x = 24 / 1620 = 2/135
hope this helps you.
this above question is answered by a meritnation expert,bt the answer given by mam is not the same answer given in rd sharma guide.itz different,the answer given in guide is 22 while answer is 2/135....so which should i follow....plzz any1 du help meee.....expertz plzzz clear my doubt...plzzz..!!
