Q).1 The difference between simple and compound interest on a some of money at 5% per annum is Rs. 25. What is the sum. a) Rs. 5000 b)Rs 10,000 c) Rs 4000 d) Data Insufficient
Q).2 If Rs. 58 is divided among 150 children such that each girl and each boy gets 25 p and 50 p respectively. Then how many girls is there ? a) 52 b)54 c)68 d)62 (Solve using concepts of Ratio,Proportion and Variation.As this Q is frm this chapter.I have solved it without using R,P&V;,eqns r 25x+50y=5800,x+y=150)
----------------------------------------------------------------------- What i think on the First Q. is that it is wrong. As we know the diff is (P*r^2)/(100^2) for t=2 yrs( Which is not given). If we use it we will get option b) as ans, which is the ans in A.S.------------------------------------------------------------------------- If anybody would like to discuss on this problem, i m readily available.
What u guys think?

The ratio between radius or the diameter is always same... And Moreover, we both are using the same methods. h=(3*a)/2 . R = 2h/3 = a/ 3 r=h/3 = a/23 You ain't using the correct formula. Hence, the ratios are 1:2:3
Hey !
Even if you just draw a simple diagram ..The height is a combination of the raddi of incircle and circumcircle ...Hence 2:4:3 seems correct to me - if the ratio is wrt dia and not radii

hey can anyone give me the working steps of these questions???? 1)Find the average of first 97 natural numbers? 2)Find the average of first 10 multiples of 3?
Hey RVP10,
There is a simpler way of working it out. Average of 1st n numbers = (n+1)/2 ... Hence for 97 : (97+1)/2 = 49 Similarly for the 2nd question : if you take 3 as a common factor then it is
