find the largest no which divides 615 and 963 leaving the remainder 6 in each case |
|
Answer» To find the largest number which divides 615 and 963 leaving remainder 6 in each case i.e. HCF.Consider HCF be x.In order to make 615 and 963 completely divisible by x, we need to deduct the remainder 6\xa0from both the cases.609 = 3 x 3 x 29957= 3 x 11 x 29⇒ x = 3 x 29 = 87∴\xa0largest number which divides 615 and 963 leaving remainder 6 in each case is 87.

Use Euclids division algorithm to find HCF 135and225 |
|
Answer» 135 and 225 Since 225 > 135,we apply the division lemma to 225 and 135 to obtain225 = 135 × 1 + 90Since remainder 90 ≠ 0, we apply the division lemma to 135 and 90 to obtain135 = 90 × 1 + 45We consider the new divisor 90 and new remainder 45, and apply the division lemma to obtain90 = 2 × 45 + 0Since the remainder is zero, the process stops.Since the divisor at this stage is 45,Therefore, the HCF of 135 and 225 is 45. 45 45 |

If an odd number p divides q2 then will it divide q3 also?? Explain. |
| Answer» Smallest odd prime number = 3Smallest odd composite number = 9H.C.F. of (3, 9) = 3L.C.M. of (3, 9) = 9As odd number p divides q².⇒ p is a factor of q² or q²/p gives 0 as a remainder.Now,\xa0q²\xa0× q = q³, and p is a factor of q², hence it will also be a factor of q²\xa0× q.⇒ p is a factor of q³Therefore, p will divide\xa0q³ also.In general, we can say that if p divides q² then it will also divide qⁿ, where n is a natural number (n ≥ 2). | |

The taxi fare after each km when the fare is Rs15 for the first km and Rs 8 for each additional km |
| Answer» No, because the total fare (in Rs.) after each km is 15,(15+ 8), (15 + 2 x 8), (15+ 3 x 8),…= 15,23, 31, 39,…Let t1\xa0= 15,t2\xa0= 23,t3\xa0= 31 and t4\xa0= 39Now, t2\xa0- t1\xa0= 23 - 15 = 8t3\xa0- t2\xa0= 31 - 23 = 8t4\xa0- t3\xa0= 39 - 31 = 8Since, all the successive terms of the given list have same difference i.e., common difference = 8Hence, the total fare after each km form an AP. | |
