For what value of m will the system of equations 17x+my+102=0 and 23x+299y+138=0 have infinite number of solutions?
A rectangular park is 120 m long and 104 m wide. A 1-m wide path runs along the boundary of the park, remaining completely inside the park area. Thus, the outside edges of the path run along the boundary wall of the park. The inside edges of the path are marked with a white line of negligible thickness. If it costs ₹2.50 to mark each metre with the white line, then how much would it cost (in ₹) to fully mark the inside edges of the path?

The difference of simple interest from two banks on ₹8,000 in 3 years is ₹800. If the rate of interest per annum in two banks are R1 and R2, then what is the value of R1 -R2? (Where R1 > R2)
If $$\tan(A + B) = \sqrt{3}$$ and $$\tan(A - B) = \frac{1}{\sqrt{3}}; 0' < (A + B) < 90^{\circ} A > B$$, then the values of A and B are ___________Â respectively.
Two ships are on the opposite of a light house such that all three of them are collinear. The angles of depression of the two ships from the top of the light house are $$30^{\circ}$$ and $$60^{\circ}$$. If the ships are $$230\sqrt{3}$$ m apart, then find the height of the light house (in m).
