Suresh has a wooden board in the shape of a triangle with sides 6 cm, 8 cm and 10 cm. He rotates the board around one of its sides by moving the vertex opposite that side. What is the minimum volume (in cm3 )of the region formed by the rotation of the board?

Out of 20 consecutive natural numbers, in how many ways can 4 numbers be selected, such that any two among the selected numbers differ by at least 3?
a) 20C3/3
b) 17C4
c) 23C4 d) 14C4
g(x)=|(ax)^m|+c
h(x)=|(bx)^(m+1)|+c
x belongs to [-10,10]-{0}
a,m belongs to natural number.
If g(x) is greater than h(x) for at most 5% of the possible values of 'x', the number of values that 'a' can have is
a 1
b 0
c 3
d 4
How to complete all tpics n quant within this month .can u people suggest some tips
For a positive integer n, let p denote the product of the digits of n and s denote the sum of the digits of n. The number of integers between 100 and 1000 for which p + s = n is
In triangle PQR, PQ = 12, QR = 16, PR = 20 and QS is the altitude from Q to PR. If a circle is drawn with centre Q and radius QS, such that it cuts PQ at U and QR at T, find the ratio PU : TR.
This is question from AIMCAT 1613(FYI). I have the solution.
I am having a doubt as to why is the triangle not considered right angled while solving?
