Question no 68 too
Do u have solution for first i think may be some misprint in problm from where we have to make tangent i think 1 point should be given nd 2 tangent we can draw outside point and one tangent is tangent at vertex i am not sure is this question correct??
@Hari_Shankar sir is problem correct??
If we draw tangent all will be variable how we can get equation of circle
@abhijit_2020 kindly confirm
But i can see only see this tomorrow as we can't see solution till test window ends and it will end today 12 am
Till then tell about second question
For 2nd it is just asking no. of square in 9x9 square grid
Then how to find then
Sum of squares till 9 =285
For MxN grid no. of square is MxN + (M-1)x(N-1) + (M-2)x(N-2)+...
That is a geometric property satisfied by a parabola
