A cylindrical box P, of height 80 cm, placed vertically on its base, contains eight identical balls stacked one on top of the other. Another cylindrical box Q, of height 108 cm, placed vertically on its base, contains 12 identical balls stacked one on top of the other. If the radius of each ball is equal to the radius of the box in which it is placed, and the top most ball in each box just touches the lid of the box, then find the ratio of the volume of each ball in P and that in Q.
In Δ ABD, ∠B = 60°, ∠D = 90° and AB = 4 cm. C is a point on BD, such that DC = DA. M is a point on CA (between C and A) such that 2CM = MA. N is the midpoint of BM. If Line CN intersects AB at P, find BP.
a,c belong to set (2,4,6,8,10,12)
b belongs to (22,24,26). find no. of equations of the form ax^2 + bx + c = 0 having real roots.

Please give explanation as well I the comment
the sum of the co-effecients of the polynomial (x-1)^5 * (x-2)^4 + (x+1)^6 * (x-2)^5 + (x+1)^2 * (x+2)^3
Ram, Shyam and Tarun started travelling from city P to city Q at the same time. Tarun took Ram on his moped while Shyam started on foot. Tarun dropped Ram on the way and asked him to walk the remaining distance to Q. He drove back till he met Shyam. He picked him up and drove to Q. All the three reached Q simultaneously. Both Ram and Shyam walk at 6 kmph while Tarun's moped travels at 30 kmph. PQ = 168 km.
Find the distance (in km) from Q that Tarun dropped Ram.
