'A' sold an article to 'B' at a profit of 20%. 'B' sold the same article to 'C' at a loss of 25% and 'C' sold the same article to 'D' at a profit of 40%. If 'D' paid Rs 252 for the article, then find how much did 'A' pay for it?
Let the article costs 'X' to ACost price of B = 1.2XCost price of C = 0.75(1.2X) = 0.9XCost price of D = 1.4(0.9X) = 1.26X = 252Amount paid by A for the article = Rs. 200.

A sum of money becomes 7/6 of itself in 3 years at a certain rate of simple interest. The rate per annum is ?
Let sum = S. Then, amount = 7S/6

If the mean of a, b, c is M and ab + bc + ca = 0, then the mean of a2+b2+c23 is :
We have : ( a + b + c) / 3 = M or (a + b + c) = 3M.
Now. a+b+c2=3M2=9M2 .
<=>a2+b2+c2+2ab+bc+ca=9M2
a2+b2+c2=9M2 ,(ab+bc+ca=0)
Required mean =a2+b2+c23=9M23=3M2 .
