**Ques:- The numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 must be put in the depicted triangle, in such a way that the sums of the numbers on each side are equal. How should the numbers be arranged in the triangle?**

**Recent Answer**: :

Average = (1+2+3+4+5+6+7+8+9)/3

= 45/3 = 15

Every side will contain sum of 15.

1st side contains 8 and 7.

2nd side contains 9 and 6.

3rd side contains 1,2,3,4 and 5.

**Ques:- Let S be the set of prime numbers greater than or equal to 2 and less than 100. Multiply all the elements of S. With how many consecutive zeros will the product end?**

**Recent Answer**: :

To determine how many consecutive zeros the product of S will end with, we need to find the highest power of 10 that divides the product. This is equivalent to finding the highest power of 5 that divides the product, since the number of factors of 2 will always be greater than the number of factors of 5.

The primes in S are {2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97}.

There are 24 primes in S, so the product of S is:

2 x 3 x 5 x 7 x 11 x 13 x 17 x 19 x 23 x 29 x 31 x 37 x 41 x 43 x 47 x 53 x 59 x 61 x 67 x 71 x 73 x 79 x 83 x 89 x 97

We need to find the highest power of 5 that divides this product. To do this, we count the number of factors of 5 in the prime factorization of each number in S.

5 appears once: 5

5 appears once: 25

5 appears once: 35

5 appears once: 55

5 appears once: 65

5 appears once: 85

So, there are six factors of 5 in the product of S. However, we also need to consider the powers of 5 that arise from the factors 25, 35, 55, and 65.

25 = 5 x 5 appears once: 25

35 = 5 x 7 appears once: 35

55 = 5 x 11 appears once: 55

65 = 5 x 13 appears once: 65

Each of these numbers contributes an additional factor of 5 to the product of S. Therefore, there are 6 + 4 = 10 factors of 5 in the product of S.

Since each factor of 5 corresponds to a factor of 10, we know that the product of S will end with 10 zeros. Therefore, the product of S will end with 10 consecutive zeros

**Ques:- H.C.F of 12, 16, 18 and 24?**

**Ques:- 1. A plane travels 695km with wind and 498km aginst the wind in same time.The speed of wind is 21km/hr. Find the speed of plane?**

**Recent Answer**: :

127.179(app)

given distance of the train along the wind is 695

and againt the wind is 498

and time = distance/speed

as we know that time is equal in both the cases hence equate

695/s1=498/s2———–(1);

where s1=speed of the plane + speed of the wind

and s2=speed of the plane -speed of the wind

given that speed of the wind is 21k/h

s1=sp+21

s2=sp-21

substitu in eq 1

we get the answer as 27.17(app)
