A bamboo stick is 2m long. 75 cm of it is coloured red and rest part coloured white. (i) find the ratio between the total length of bamboo and the portion painted red.

A bamboo stick is 2m long, 75 cm of it is coloured red and rest part coloured white. (ii) Let's find the ratio between the total length of bamboo and the porition painted white.

A bamboo stick is 2m long, 75 cm of it is coloured red and rest part coloured white. (iii) Let's find the ratio between the part colooured red and coloured white.

Let us take a rectangular piece of white paper and let's draw 10×10 equal cells. Now 0.19 part is coloured red and 0.23 part is coloured green. Let's find the percentage of the cells which are not coloured.

frac(1)(3) rd part of the length of a bamboo is coloured red, and frac(1)(5) th part of it is coloured green and the remaining 14m length is coloured yellow. Let's find the length of the bamboo.

Two identical charged particles are fastened to the two ends of a spring of stiffness 100 N/m and natural length 10 cm. The system rests on a smooth horizontal table. If the charge on each particle is 2times10^(-8)C , find the extension in the length of the spring, when the system is in equilibrium assume that extension is small as compared to the natural length.

Concentric circles of radii 1,2,3,. . . . ,100 c m are drawn. The interior of the smallest circle is colored red and the angular regions are colored alternately green and red, so that no two adjacent regions are of the same color. Then, the total area of the green regions in sq. cm is equal to 1000pi b. 5050pi c. 4950pi d. 5151pi

From a bamboo of length 15.77 m, 2.55 m is cut off. The reaining part is divided into 4 equal parts. Let's find the length of each part.

A 2m long metallic wire is broken into two unequal points P and Q. P part of the wire is uniformly extended into another wire R. Length of R is twice the length of P and resistance of R is equal to that of Q. Find the ratio of resistances of P and R and also the ratio of lengths of P and Q.
