6. ABCD is a square. P is the midpoint of AB. The line passing through A and perpendicular to DP intersects the diagonal at Q and BC at R. If AB = 2 then PR = ______ ?
coefficient of x^18 in the expansion (x+x^2+x^3+....+x^6)^4 ?
(x+x^2+x^3+....+x^6)^4 =>x^4*(1+x+x^2+x^3+....+x^5)^4 =>x^4*(1-x)^-4*(1-x^6)^4 =>x^4*(3C3+4C3x+5C3x^2+.....)*(1-4C1x^6+4C2x^12) =>x^4*(17C3x^14+4C2*5C3x^14-4C1*11C3x^14) =>740-660=80 PS:@gautam22 guess so... nd wht i tld u no sir
DS: The base of a triangle is 60 cms, and one of the base angles is 60째. What is length of the shortest side of the triangle? I. The sum of lengths of other two sides is 80 cms. II. The other base angle is 45째.

It takes six days for 3 women and 2 men, working together, to complete a work. 3 men would do the same work 5 days sooner than 9 women. How many times does the output of a man exceeds that of a woman?

The weight of an iron bucket increases by 33.33% when filled with water to 50% of its capacity. Which of these may be 50% of the weight of the bucket when it is filled with water( assume the weight of bucket and its capacity in kg to be integers?.. plz explain in detail with steps.
There are 2 buses running from terminuses A nd B, each bus making 5 round trips in a day with no stops in btw.These buses ply on the same route with diff but uniform speeds. Each morning the buses start at 7am from their respective terminuses. They meet for teh 1st time at a dist of 7km from A and. Thier next meeting takes place at a dist of 4km from B, while travelling in opp directions.Assuming that the time taken by the buses at the terminuses is negligible and the cost of running a bus is Rs20/km.Find the daily cost of running the buses. 3200 4000 6400 6800 none @YouMadFellow
