Let the initial amount with them be Rs. x and Rs. y respectively. 

Then according to the question:

x+100=2(y−100)

x+100=2y−200

x−2y=−300…(1)

And,

6(x−10)=(y+10)

6x−60=y+10

6x−y=70…(2)

Multiplying equation (2) by 2, we get:

12x−2y=140…(3)

Subtracting equation (1) from equation (3), we get:

11x=140+300

11x=440

x=40

Substitute the vale of x in  equation (1), we get:

40−2y=−300

40+300=2y

2y=340

{tex}y=\frac{340}{2}=170{/tex}

∴ The  friends had Rs. 40 and Rs. 170 with them respectively.

Who hasn't heard of the great American inventor Thomas Edison!

His inventions include the gramophone and the electric lamp.  

He invented the gramophone at the age of thirty-one only.  

Later, he invented the electric bell.  

One of his jobs was to improve the telephone first invented by Graham Ball.  

Do you know how much he earned by improving it?  

A company called Western Union paid 1,00,000 for him.  

He had to carry out six thousand tests to make a good electric bulb.  

How much patience it must have needed!  

Try to get inspiration from the life of Edison.

Lomov was a funny man. He was physically weak but financially secure. He was suffering from palpitation. He behaved as if he were eccentric. He was a pretentious, proud, self-serving, argumentative, impetuous and hysterical hypochondriac. He was socially awkward and prone to anxiety attacks. He was not particularly romantic, and his proposal had more to do with the economic advantages of combining the families' adjacent properties than with any particular degree of love for Natalya or with the desire to get married. He was regressive in his thoughts. It was evident from his attitude towards marrying Natalya. He wanted to marry her not because he was in love with her but because he thought that she was beautiful and a good-housekeeper. But when he went to propose to her, he got diverted. Actually, a quarrel took place between them as Natalya thought that he had come to claim Oxen Meadows as his own. They quarrelled over petty issues one more time. This reflected that he was short-tempered also. He fainted before finally proposing to her and shouted a lot after that. This reflected that he was confused and less confident. But he finally succeeded to get acceptance.
