RBI Assistant Model Paper 6

Let total quantity of mixture initially = 100x
So quantity of milk initially = 75x
So quantity of water initially = 25x
8 liter of mixture is taken out
So,

8×75

100

= 6 liter of milk is taken out
8−6 = 2 liter of water is taken out
Now,
ATQ,

75x−6+7

25x−2

=

7

2

x =

16

25

So initial quantity of mixture =

16

25

×100 = 64 L
