previous no of pages ?
E)None of these
20%
30%
40%
50%
Explanation:
45×30×60 = X×40×32
Page =X = $\dfrac{45 \times 30 \times 60}{40 \times 32}$ = 63.28 = 63
63 – 45 = 18
(18/45)×100 = 40%
45×30×60 = X×40×32
Page =X = $\dfrac{45 \times 30 \times 60}{40 \times 32}$ = 63.28 = 63
63 – 45 = 18
(18/45)×100 = 40%
