A student can divide her books into groups of 5, 9 and 13. what is the smallest possible number of the books ?
The smallest possible number of books = L.C.M of 5, 9 and 13.Therefore, L.C.M of 5,9 and 13 is = 5 x 9 x 13 = 585.

A bag contains 3 red balls, 5 yellow balls and 7 pink balls. If one ball is drawn at random from the bag, what is the probability that it is either pink or red?
Given number of balls = 3 + 5 + 7 = 15
One ball is drawn randomly = 15C1
probability that it is either pink or red = 7C1 + 3C115C1 = 7 + 315 = 1015 = 23

For x∈N, x>1, and p=logxx+1, q=logx+1x+2 then which one of the following is correct?
kl>k+1l+1 for (k,l) > 0 and k > l
Let k = x+1 and l = x
Therefore, x+1x>(x+1)+1(x)+1
(x + 1) > x
Therefore, log(x+1)log(x)>log(x+2)log(x+1)
⇒logxx+1 >logx+1x+2
The sides of a right-angled triangle are 12 cm, 16 cm, 20 cm respectively. A new right angle Δ is made by joining the midpoints of all the sides. This process continues for infinite then calculate the sum of the areas of all the triangles so made.
