`(4)/(9)` of a pole is in the mud.When `(1)/(3)` oft is pulled out, 250cm of the pole is still in the mud length of the pole (a) 1000cm, (b) 1100cm, (c) 950cm (d) 1050

Position of the image when the object is at a distance 30 cm from the pole is -

The sides of a triangle are in the ratio of (1)/(2):(1)/(3):(1)/(4) .If the perimeter is 52cm, then the length of the smallest side is (a) 9cm(b)10cm (c) 11cm(d)12cm

Altitude on the hypotenuse of a right angle triangle divides it in two parts of length 4 cm and 9 cm. Find the length of the altitude. a) 9cm b) 4cm c) 6cm d) 18cm

frac(1)(5) part of a pole lies in mud, frac(3)(5) part lies in water and the remaining 5 metres lies above the water. Let's find the length of the pole and write it.

(1)/(10) of a pole is coloured white,(1)/(20) is coloured red,(1)/(30) is coloured green and the rest is coloured black.If the length of the black portion is 14m 70cm,then find the length of the pole.

If the magnetic moment of a bar magnet of length 5 cm be 1A.m^(2) , what is the strength of each pole ?
