84/11 ??
@sh.arora10 said:19
19 nahi ho sakta agar aisa hota hai to number of males is 14 and females is 5. 2% of 14 and 59% of 5 dono he integer nahi aayenge. for these values to be integers 1900 should be the answer
@sh.arora10 said:19
yaar eqn wise19 ho sakta hai
but logically kaise ho sakta hai
it means 5 females & 14 males
Now 2% of males in this case is not coming to be a natural no.
@007pagal said:i solved it but the calculations were lengthy
approach kya tha?? did u also use similar trian concept
@rahulshaitan said:is the answer 84/11????
Bro did u also encounter lenghty caln?
if not kindly share ur approach

ho sakta hai answer galat ho ya yeh solution wrng ho.........
plz go thru d solution..
Let total no. of people = n
males = x, females = n-x
according to the given condition
2x/100 + 59(n-x)/100 = 17n/100
or 2x + 59(n-x) = 17n
or 2x + 59n -59x = 17n
or 42n = 57x
or n = 57x/42
for finding minimum number of people, take x = 14 (here 14 is the least integer for which n is integer)
n = 57*14/42 = 19

@mickym said:approach kya tha?? did u also use similar trian conceptno i used the cosine formula by which we find an angle when all three sides are given
gudnite guys

But 2 % of 14 is not a natural no.
Neither is 59 % of 5.......WAt say???

bhai calculation lenghty thi but me post karta hu solution :)
@rahulshaitan
bro the square side lying on the side BC
whenever i see that lying on the side i will get diff thoughts if u don`t mind will u explain what that means exactly

see the attachment for solution. kuch samajh na aaye to puch lena kyunki meri handwriting bahut gandi hai :)
