I was not getting the concept of this trick clearly I was confuse from the second line.

For example 1000 - 357 = 643

We simply take each figure in 357 from 9 and the last figure from 10.

If you can clarify then please clear this line so that I can understand this trick.

Yes, I should have clarified. After you use the specified formula, you get the Rational # in between by: x+d, x+2d, x+3d...x+nd. To give an example, lets say we have to find 3 rational numbers between 2 and 3. Therefore: x=2 y=3 n=3. Thus, d= (3-2)/(3+1)=1/4. So the n numbers are: 2 1/4, 2 2/4 and 2 3/4. This is fairly obvious, I just wanted to give the generalized formula.

Yes I agree with you I also use this formula of rational number and I got the actual answer.

Thank for sharing. Now i can also calculate only in 3 minutes.

Not getting the question, geometrical question is not getting me properly.

If I am remembering it right, the y intercept is the fixed cost. You are correct that is b.

Yes agree, you are exactly correct. Y intercept is the fixed cost.

The formula is very nice, once we start solving the question by using the above formula, then we can easily remember the above formula. Not too difficult to remember the above formula.

It is not easy to remember all this formula, few formula we can remember because there are some formulas which are like some basic formulas which we can use sometimes.

Answer is "the same" if two lines intersect on more then one point then they are in the same.

MULTIPLES OF 3

3 times even number

Rule

a. Write half of the multiplier and put 0 at the end.

b. Double the multiplier and subtract it from Rule (a).Examples:

3 x 4; Half of 4 is 2. Put 0 at the end to form 20.

Take away twice the multiplier. Twice of 4 is 8. 20-8 = 12.

Therefore 3 x 4 = 20.

All the rules are excellent and correctly giving the answer. But the above rule is not getting me properly I think it is wrong please give the correct rule for above.

Celsius to Fahrenheit is not 9/5 of (C+32) Nor (C+32)x9/5.

It is (9/5 of C)+32.

For example 0C is 32F, as the most obvious example. 9/5 of (0C+32) is not equal to 32F, but (9/5 of 0C)+32 is equal to 32F. The formual (9/5 of C)+32 also works on other perhaps obvious examples, like 100C is 212F and -40C is -40F.

Yes you are right, the formula posted in thread was wrong, only right hand side is correct left hand side is not correct. The correct formula is that which is posted by you.
