bhai go straight way adding taking root wala fractions on one side..
{(x-a)-(x-b)}/rt((x-b)(x-a) = (b-a)/x ..... square
x^2 = x^2-x(a+b) +ab .... x = ab/(a+b) ...............Ans

Bhai 960
Let boys 5x Gals 3x
new boyz 5y galz 7y
8x+12y=1200.........1st
also (5x+5y)/(3x+7y) = 7/5
=> x= 6y
hence put this in 1st
y=20
x= 120
total 8*120= 960
@sampras bhai is question ko hum options se chalu karte toh jaldi ho jata

yaar manually calculate karne k alawa koi faster method.....????
@gudda1122 said:

ha bhai

Iske liye we use tha fact That A& C both are finishing earlier than B&C;
So A ke Days less hi hogen B se

So 10,15,30
@sumitrewri said:

nahi bhai
assume salary be a .....b ....c

now saving will be
.20a
.15b
.25c

hence ratio of a...b....c...is 4:3:5
so a=4800
@watsnew24 bhai hum bhi likh kar karte hai...koi shortcut nai hai mere pas
@sumitrewri yr salary walla ka answer......3200,4800,6400 hai kya??
@sumitrewri
