We have,
(99)3 =(100−1)3
We know that
(a−b)3=a3−b3−3ab(a−b)
Therefore,
=(100)3−13−3×100×1×(100−1)
=1000000−1−300(100−1)
=1000000−1−30000+300
=970299

The Rattrap man happens to get refuge for a night shelter at the Ramsjo Iron works. By chance the owner mistakes him as an old acquaintance and inuites to spend for the Christmas eve but the Rattrap declines his offer. The ironmaster sends his daughter Edla to bring and persuade the mar at their house. Haring milk of human kindness flowing in her body, she finds the peddler in a very miserable condition through her kind, considerate and persuasive power, she gets success in taking the peddler alongwith her. She promises to him to leave as and when he desires. Being a perfect host, she takes every care to make her guest feel comfortable at home. She is a practical and fine observer of people. She immediately tells her father that the peddler seems to be both an uneducated and thief. But the father points out that the stranger will be fine after properly dressed.
When the truth is known, the ironmaster becomes ugly and threatens to call the shrieft. He orders to peddler to leave away at once. But Edla intercedes for the vagabond and lets her father concede for his proper stay till the Christmas Eve. She is against chasing away a person whom they have invited for a promised “Christman Cheer”. Her persuasive powers make the stranger surrender to her wish. She is happy when the peddler leaves for her with a Christmas present and a thirsty kroner note. In his letter to Edla, he thanks for being so, nice to him. He finally thanks her saving him from falling into the “world’s rattrap”. It is thus, the love and understanding brings out a basic human goodness in the peddler.

William O. Douglas was born in 1898 at Maine. After graduating he adopted the profession of teaching but he soon got tired of this job and adopted the legal career. He served in the court as a justice for a longer period of life. Since childhood he had a mind for swimming but he got aversion for water when a wave swept over and buried him. On the second occassion at the age of ten or eleven, a big burly boy tossed him up and threw deep in the pool that created stark fear in his mind. He made three attempts but every time he went down deeper and deeper. He became unconscious when he got up he was vomiting beside the pool.
The terror of water followed him wherever he went. To get rid of it, he made a strong determination. He decided to overcome his fear through his ‘will’. He engaged an instructor who perfected Douglas in swimming. He gave him hundreds of exercises and taught him to exhale and inhale in water. The practice went on for three months and Douglas was able to recede his terror. Then after more exercises, the instructor ordered him to dive himself. He swam across and back the lake. He was now completely out of fear. He stated that a fear is nothing but all we have to fear is fear itself. Its reality it is the “will to live” that removes all our fears, terrors, troubled and difficulties in case we struggle hard and make a strong determination to materialize it.

Perimeter of isosceles triangle=30cm
Length of equal sides=12cm
Let third side of triangle=xcm
According to problem,
x+12+12=30
x+24=30
x=30−24
x=6
∴ Third side of triangle=6cm
Using Heron's formula
Area of triangle= √s(s−a)(s−b)(s−c) sq. units
where s= a+b+c/2
s= 30/2 =15
Area of triangle= √15(15−12)(15−12)(15−6) cm²
= √15×3×3×9 cm²
=3×3× √15cm²
=9√15cm²
∴ Area of triangle=9√15 cm

Trangenic animals are the animals with the modified genome. A foreign gene is inserted into the genome of the animal to alter its DNA. This method is done to improve the genetic traits of the target animal.
Initially, the improvement of genetic traits was done by selective breeding methods. In this, the animals with desired genetic characteristics were mated to produce an individual with improved genetic characteristics. Since this technique was time-consuming and expensive, it was later replaced by recombinant DNA technology.
