ICSE − Q & A

(Hey Maths Wizards help this maths monster)
1) In a GP 3rd term is 24 and 6th term is 192. Find 10th term (my answer is 82944 x root3)
2) Which is better installment 8%Rs.50 share at 40 or 10% Rs 100 share at 120 (my answer is second one)
3) is writing 2:3 or 3:2 in line intersection ratio same ?

In linear inequations,
P Intersection Q' is essentially the same thing as P-Q right?

Proofs of theorems are not in syllabus, right? 
I just want to confirm.

Our teacher told us to steer clear of the Ogive question since there's a large possibility of human-error (the hand made graph). Thoughts?

Also, guys don't forget to write theorems, formulae,etc on the right hand side, lest should lose a mark! And 99 hurts..

Is sample space compulsory in every probability question?

when two dice are rolled simultaneously what is the possibility of getting:
a multiple of two on one die and a multiple of three on the other.

cosec6A -cot6A= 3cot2A.cosec2A+1

Please prove it!!!

Okay so just rechecking. Say we get a squareroot of a prime no. And it can't be simplified. We can use the log book to find the squareroot right?
Also Can y'all name the chaps where even if the squareroot is coming as the answer, we gotta show the working?

the nth term of an AP cannot be n2 +n+1.justify your answer
