For Q 2 I got 93 values but as 90 was the closest, opted for that.

For Q 10 I think it’s one of the last three options 183, 184 or 185.

6) A semicircle is inscribed in a right triangle so that its diameter lies on the hypotenuse and the centre divides the hypotenuse into segments 15 cm and 20 cm long. FInd the length of the arc of the semicricle included between its points of tangency with the legs.

A) 2π B) 3π C) 4π D) 6π E) none of these

Option D – 6pi

let the radius be r
and the point of tangency be P and Q and triangle be ABC. P lies on AB and Q on BC

let AP = m and BQ = n

m^2 = 15^2-x^2
n^2 = 20^2-x^2
m = 9 and n = 16 x =12 arcPQ = 6pi

1. was very easy a-1/a = 1 and ten sum of roots. 5 second problem
4. Prade did it better. I did it by a bit of trial and error and narrowed it.
5. Easy (n-1/2)^2
6. You get the sides as 35,28 and 21 and R=12..Circumference/4
7. Did it by trial and error
8. We can easily say that its a quadratic equation. Bit of intensive calculation involved. You can avoid it by making use of the answer choices.

My take..
1)A
4)B
5)A
6)D
7)B
8)E

Most of the problems I got, I got them in 1-2 minutes. But at least 5 of them here are of QQAD standard. Great job Implex..Expect more of these from you:)
