this is very easy..
2/3X----->5/4Y
1x------>5/4*3/2 y
3/2x----> (5/4)*(3/2)*(3/2) y=45/16 y
which is option C

Say in Re. 1 he buys bread Type / Quantity as shown

Rupees ............ X ...................... Y

1 ................... \(\frac{2}{3}\) ....................... \(\frac{5}{4}\) (Quantity)

To buy 3/2 Quantity of Bread X, amount required \(= \frac{\frac{3}{2}}{\frac{2}{3}} = \frac{9}{4}\)

Bread obtained in Rupees 9/4\(= \frac{9}{4} * \frac{5}{4} = \frac{45}{16}\)

Answer = C

\(1\frac{1}{2} = \frac{3}{2}\)

\(\frac{2}{3}\) quantity of X comes in Re. 1, so \(\frac{3}{2}\) would come in \(1 * \frac{3}{2} * \frac{3}{2} = \frac{9}{4}\)

\(\frac{9}{4}\) is the amount available in hand to purchase Bread Y

\(\frac{2}{3}\)x = \(\frac{5}{4}\)y

\(\frac{3}{2}\)x = ??


\(\frac{2}{3}\) * x = \(\frac{3}{2}\)

x = \(\frac{9}{4}\)

\(\frac{5}{4}\) * \(\frac{9}{4}\) = \(\frac{45}{16}\) = 2\(\frac{13}{10}\)

OA:C

\(\frac{2}{3}X=\frac{5}{4}Y\)

\(1X=\frac{3*5}{2*4}Y=\frac{15}{8}Y\)

\(\frac{3}{2}X=\frac{3*15}{2*8}Y=\frac{45}{16}Y=2\frac{13}{16}Y\)
