Answer 2

Correct answer:- (2) 200ml, 300ml .

Formula:-

(N1 × V1) + (N2 + V2) = N × V

Given,

N1 = 1/20 N, N2 = 1/30 N , N = 1/25 N ,

V = 500ml .

To find:- V1 = ? and V2 = ?

Solution:-

$\frac{1}{20} \times v1 + \frac{1}{30} \times v2 = \frac{1}{25} \times 500 \\ = > \frac{v1}{20} + \frac{v2}{30} = 20$

Now, Observe all four options . We will find that, V1 = 200ml and V2 = 300ml .

Hope it's helpful to you.
