Yogita Ingle 5 years, 6 months ago

Let p be the number.

Suppose,

p÷4=q, remainder=2

q÷5=r, remainder=3

r÷6=s, remainder=4

Then,

r=6s+4

q=5r+3=5(6s+4)+3=30s+23

p=4q+2=4(30s+23)+2=120s+94

Let us now assume that the remainder s=1. Then we have:

p=(120×1)+94=214

Hence, the number is 214.

Vinayak Agrawal 5 years, 6 months ago

real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.

Yogita Ingle 5 years, 6 months ago

When an image is formed on a screen with the help of a mirror, it is called a Real Image. Similarly, an image which can’t be obtained on a screen with the help of a mirror, it is called Virtual Image.

Concave and convex mirrors can be used to produce real as well as virtual images.

Rayon is known as artificial silk as this fibre resembles silk in properties. It is obtained by chemical treatment of wood pulp of cotton. Rayon resembles silk, so it is also known as artificial silk. Artificial silk or rayon is produced in mills, is produced in bulk at one time and requires less labour and skill whereas original silk is produced by the silk worms and it requires a lot of skill, labour and time to treat the worms and extract silk from them. Hence artificial silk is cheaper than natural silk.
