A non-leap year has 365 days
A year has 52 weeks. Hence there will be 52 Sundays for sure.
52 weeks = 52 x 7 = 364 days .
365– 364 = 1day extra.
In a non-leap year there will be 52 Sundays and 1day will be left.
This 1 day can be Sunday, Monday, Tuesday, Wednesday, Thursday,friday,Saturday, Sunday.
Of these total 7 outcomes, the favourable outcomes are 1.
Hence the probability of getting 53 sundays = 1 / 7.
∴ probability of getting 52 sundays = 1 - 1/ 7 = 6 / 7.

Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone.
Volume of the frustum of a cone = (1/3) πh (r12 + r22 + r1 r2)

We have seen that a quadratic polynomial is of the form:
p(x):ax2+bx+c,a≠0,
We assume that a, b and c are real numbers. In general, this polynomial has two zeroes. For example, the polynomial p(x):x2−3x+2 has the zeroes x=1,2
.For some quadratic polynomials, the two zeroes might be equal. For example, the polynomialp(x):x2−4x+4
can be rewritten as p(x):(x−2)2. Thus, we can say that this polynomial has the two zeroes: x=2,2,
which happen to be identical.
There might also be quadratic polynomials which have no real zeroes. Consider the polynomial p(x):x2+1
. For no real value of x can this polynomial take zero value, which means that this has no real zeroes. Note that this does not mean that the polynomial does not have any zeroes. Of course this polynomial has (two) zeroes – however, those zeroes are just not real numbers.

Cut a right circular cone with a plane parallel to the base of the cone, then the solid shape between the plane and the base of the cone is called the frustum of a cone.
e.g. Flower pots have a shape as the frustum of a cone.
The surface area and the volume of the frustum of a cone can be calculated using standard formulae.
CSA of the frustum of a cone = πl( r1 + r2).
where r1 = radius of the larger circular face of the frustum, r2 = radius of the smaller circular face of the frustum, and l = slant height of the frustum.l = h2+(r1-r2)2 and h is the height of the frustum.
TSA of a frustum of a cone = πl(r1 + r2) + πr12 + πr22

Given numbers are 455 and 42
Here, 455 > 42
So, we divide 455 by 42
By using Euclid’s division lemma, we get
455 = 42 × 10 + 35
Here, r = 35 ≠ 0.
On taking 42 as dividend and 35 as the divisor and we apply Euclid’s division lemma, we get
42 = 35 × 1 + 7
Here, r = 7 ≠ 0
So, on taking 35 as dividend and 7 as the divisor and again we apply Euclid’s division lemma, we get
35 = 7 × 5 + 0
The remainder has now become 0, so our procedure stops. Since the divisor at this last stage is 7, the HCF of 455 and 42 is 7.

3x-y-5=0
so 3x-y=5 (1st equation)
now multiply the equation by 2
(3x-y=5)×2
= 6x-2y=10
but as per the question
6x-2y-p=0
6x-2y=p
substitute the equations
p=10
