Two persons 'A' and 'B' together can finish a piece of work in 16 days while 'B' and 'C' together can complete the same work in 20 days. If 'A' , 'B' , 'C' work together, the same work is completed in 12 days, then the number of days required for 'A' alone to complete the work is

If 'P' and 'Q' can do a piece of work in 18 days, 'Q' and 'R' can do it in 24 days, 'P' and 'R' can do it in 36 days, then the time (in days) needed by 'P' alone to finish that work, is

A window is in the shape of a rectangle surmounted by a semicircle on the length side of the rectangle. If the dimensions of the sides of the rectangle. If are 16 cm and 6 cm, then the area of the that window, in square centimetres, is

If the perimeter and diagonal of a rectangle are 18 m and 5 m respectively, then the area of that rectangle (in sq. meter) is

Three circles of radius 8 cm each are touching each other externally. Then the area (in sq. cm) inside the triangle formed by joining their centres that is covered by the 3 circles is

If the angle of a sector of a circle of radius 21 cm is $$75^{\circ}$$, then the perimeter of that sector approximately (in cms)

The floor area of a conical shaped tent is 154 sq.m and its vertical height is 24m. If each square meter of canvas costs Rs. 15.50, the approximate cost of the canvas needed for the tent (in Rs) is
