Two boys are running on two different circular paths with same centre. If their radii are 5m and 10m, the maximum possible distance between them is (a) 5 m         (b) 10 m     (c) 15 m      (d) 20 m

The ratio of the outer and the inner perimeters of a circular path is 23 : 22. If the path is 5 metres wide, the diameter of the inner circle is (a) 55 m (b) 110 m (c) 220 m (d) 230 m

If the area of an acute-angled triangle is 75 m^(2) and two of its sides are 20 m and 15m, then the angle between them is

If the area of trapezium is 250m^(2) , then the distance between the parallel sides of lengths 15 m and 10 m, is

If the area of trapezium is 250 m^(2) , then the distance between the parallel sides of lengths 15 m and 10 m, is

There are two towers of 5m&10m. The line joning there tops makes 15^(@) with ground then find the distance between them

Two poles of height 9 m and 15 m stand vertically upright on a plane ground. If the distance between their tops is 10m, then find the distance between their feet.

Three boys are standing on a circular boundary of a fountain.They are at equal distance from each other.If the radius of the boundary is 5m, the shortest distance between any two boys is (a) (5sqrt(3))/(2)m(b)5sqrt(3)m (c) (15sqrt(3))/(2)m(d)(10backslash pi)/(3)m

Two poles of the height 15m and 20 m stand vertically upright on a plane ground. If the distance between their feet is 12 m, find the distance between their tops. Options are (A) 11 m (B) 12 m (C) 13m (D) 14m.

A circular road runs around a circular garden. If the difference between the circumference of the outer circle and the inner circle is 44 m, the width of the road is (a) 3.5 m (b) 4 m (c) 7 m (d) 7.5 m

Two poles of heights 6 m and 11 m stand vertically on a plane ground. If the distance between their feet is 12 m, the distance between their tops is 13 m (b) 14 m 15 m (d) 12.8 m
